What is another name for a circle graph?
pie graphAlso called circle graph, pie graph..
How do you find the radius of a circle given two points?
Substitute (x1,y1)=(h,k),(x2,y2)=(x,y) and d=r . Square each side. The equation of a circle with center (h,k) and radius r units is (x−h)2+(y−k)2=r2 .
What is the equation of a straight vertical line?
The equation of a vertical line always takes the form x = k, where k is any number and k is also the x-intercept . (link) For instance in the graph below, the vertical line has the equation x = 2 As you can see in the picture below, the line goes straight up and down at x = 2.
How do you translate units on a graph?
Transformations of Graphs A graph is translated k units vertically by moving each point on the graph k units vertically. g (x) = f (x) + k; can be sketched by shifting f (x) k units vertically. if k < 0, the base graph shifts k units downward.
Is a circle on a graph a function?
A circle is a set of points in the plane. A function is a mapping from one set to another, so they’re completely different kinds of things, and a circle cannot be a function. … The graph of a function, , is the set of pairs, for all in the domain, which can be interpreted as points in a plane.
What is the function for a circle?
This circle is known as a unit circle. then the cosine of the angle would be the x-coordinate and the sine of the angle would be the y-coordinate. Since both the coordinates are defined by using a unit circle, they are often called circular functions. Solve the equation sin v = 0.5 with the unit circle.
Can a straight line be a function?
A linear function is a function whose graph is a straight line. The line can’t be vertical, since then we wouldn’t have a function, but any other sort of straight line is fine.
How do you write the standard form of a circle?
The standard form of a circle’s equation is (x-h)² + (y-k)² = r² where (h,k) is the center and r is the radius. To convert an equation to standard form, you can always complete the square separately in x and y.
How do you find the intercepts of a circle?
To find the x intercepts, set y = 0 in the above equation and solve for x. To find the y intercepts, set x = 0 and solve for y.
Is a straight vertical line a function?
For a relation to be a function, use the Vertical Line Test: Draw a vertical line anywhere on the graph, and if it never hits the graph more than once, it is a function. If your vertical line hits twice or more, it’s not a function.
How do you translate a graph with absolute value?
Absolute Value FunctionsThe absolute value parent function, written as f(x)=| x |, is defined as.To translate the absolute value function f(x)=| x | vertically, you can use the function.g(x)=f(x)+k.To translate the absolute value function f(x)=| x | horizontally, you can use the function.g(x)=f(x−h).More items…
What is the rule for translations?
Mapping Rule A mapping rule has the following form (x,y) → (x−7,y+5) and tells you that the x and y coordinates are translated to x−7 and y+5. Translation A translation is an example of a transformation that moves each point of a shape the same distance and in the same direction. Translations are also known as slides.
What equation makes a circle on a graph?
The equation of a circle appears as (x – h)2 + (y – v)2 = r2. This is called the center-radius form (or standard form) because it gives you both pieces of information at the same time. The h and v represent the coordinates of the center of the circle being at the point (h, v), and r represents the radius.
How do you describe a circle graph?
Initial Definition. A circle graph is a visual representation of data, made by dividing a circle into sectors that each represent parts of a whole. Usually the amounts in each sector are represented in percent, so that all of the amounts total 100%. Circle Graph Example.
How can you tell if a graph is a function?
Mentor: Look at one of the graphs you have a question about. Then take a vertical line and place it on the graph. If the graph is a function, then no matter where on the graph you place the vertical line, the graph should only cross the vertical line once.
What are the parts of a circle graph?
A circle graph is divided into sectors, where each sector represents a particular category. The entire circle is 1 whole or 100%, and a sector of the circle is a part.
Is every line a function?
No, every straight line is not a graph of a function. Nearly all linear equations are functions because they pass the vertical line test. The exceptions are relations that fail the vertical line test.
What is the translation rule for a graph?
The Rule for Horizontal Translations: if y = f(x), then y = f(x-h) gives a vertical translation. The translation h moves the graph to the left when h is a postive value and to the right when h is negative value.
