Front

What is a function?

Back

A function is a relation that assigns exactly one output for each input from a set of inputs.

Front

What does it mean to evaluate a function?

Back

To evaluate a function means to find the output value when a specific input is substituted into the function.

What is the output of a function when the input is zero?

Back

The output of a function when the input is zero is found by substituting 0 into the function.

Front

What is the slope-intercept form of a linear function?

Back

The slope-intercept form is given by y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the y-intercept of the function f(x) = -2x + 5?

Back

The y-intercept is 5, which is the value of f(0).
