Inverse Functions and One-to-One Functions Quiz

What is the line of symmetry used when graphing inverse functions?

• y = 0

• x = 0

• y = x

• x = y

When graphing an inverse function, what happens to the x and y values?

• They are divided by 2.

• They remain the same.

• They are flipped.

• They are multiplied by 2.

What is the first step in graphing a linear function's inverse?

• Calculate the y-intercept.

• Find the slope.

• Flip the x and y values.

• Draw a horizontal line.

How do you handle domain restrictions when graphing a quadratic function?

• Only graph values greater than or equal to zero.

• Graph the entire parabola.

• Graph values less than zero.

• Ignore them.

What does the vertical line test determine?

• If a graph is a function.

• If a graph is symmetrical.

• If a graph is linear.

• If a graph is quadratic.

What does the horizontal line test check for?

• If a graph is a function.

• If the inverse of a graph is a function.

• If a graph is linear.

• If a graph is quadratic.

Which test must a function pass to be considered one-to-one?

• Both vertical and horizontal line tests.

• Vertical line test only.

• Horizontal line test only.

• Neither test.

If a graph fails the vertical line test, what can be concluded?

• It is a linear function.

• It is a quadratic function.

• It is not a function.

• It is a one-to-one function.

What happens if a graph passes the vertical line test but fails the horizontal line test?

• It is a quadratic function.

• Its inverse is not a function.

• It is not a function.

• It is a one-to-one function.

What is the significance of the line y = x in inverse functions?

• It is the origin.

• It is the y-axis.

• It is the x-axis.

• It is the line of symmetry.
