(Assignment) X intercept and Y intercept

Front

What is the x-intercept of a function?

Back

The x-intercept is the point where the graph of a function crosses the x-axis, meaning the value of y is zero.

Front

What is the y-intercept of a function?

Back

The y-intercept is the point where the graph of a function crosses the y-axis, meaning the value of x is zero.

Front

True or false: The x-intercept of a function ALWAYS occurs where y is equal to zero.

Back

True

Front

True or false: The y-intercept of a function ALWAYS occurs where y is equal to zero.

Back

False

Front

How do you find the x-intercept of a function given its equation?

Back

To find the x-intercept, set y to zero and solve for x.

Front

How do you find the y-intercept of a function given its equation?

Back

To find the y-intercept, set x to zero and solve for y.

Front

What is the x-intercept of the function f(x) = 2x + 4?

Back

The x-intercept is (-2, 0).

Front

What is the y-intercept of the function f(x) = 2x + 4?

Back

The y-intercept is (0, 4).

Front

If a function has an x-intercept at (3, 0), what does this indicate?

Back

It indicates that when x = 3, the value of the function is zero.

Front

If a function has a y-intercept at (0, -5), what does this indicate?

Back

It indicates that when x = 0, the value of the function is -5.
