Front

Evaluate f(-2) if f(x) = x² + 3

Back

f(-2) = 7

Front

If f(x) = -3x - 8, find f(-1).

Back

f(-1) = -5

Front

If f(x) = x - 5, what is the value of x when f(x) = 15?

Back

x = 20

Front

If a question asks you to find f(2), what does that mean?

Back

Plug in 2 for x

Front

If f(x) = 2x + 1, find f(1).

Back

f(1) = 3

Front

What is function notation?

Back

A way to represent a function using symbols, typically f(x), where f is the function name and x is the input.

Front

What does f(x) represent?

Back

f(x) represents the output of the function f for a given input x.

Front

How do you evaluate a function at a specific point?

Back

Substitute the specific point into the function's equation.

Front

What is the domain of a function?

Back

The set of all possible input values (x) for the function.

Front

What is the range of a function?

Back

The set of all possible output values (f(x)) for the function.
