Domain/Range/Intercept Test Review

Front

What is the definition of the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

What is the definition of the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

How do you find the x-intercept of a linear equation?

Back

To find the x-intercept, set y = 0 in the equation and solve for x.

Front

How do you find the y-intercept of a linear equation?

Back

To find the y-intercept, set x = 0 in the equation and solve for y.

What is the x-intercept of the equation 2x - 5y = 10?

Back

(5, 0)

Front

What is the y-intercept of the equation 2x - 5y = 10?

Back

(0, -2)

Front

What does it mean if a function has no x-intercept?

Back

It means that the graph of the function does not cross the x-axis, indicating that there are no real solutions for y = 0.
