Function Notation and Evaluating Functions

Front

What is function notation?

Back

Function notation is a way to represent a function using symbols. It typically uses the format f(x), where 'f' is the name of the function and 'x' is the input variable.

How do you evaluate a function at a specific value?

Back

To evaluate a function at a specific value, substitute the value into the function's equation in place of the variable.

Front

Evaluate f(x) = 2x^2 + 5x - 17 for f(-1).

Back

f(-1) = -20

Front

Evaluate f(x) = 2x^2 + 5x - 17 for f(1).

Back

f(1) = 2

Front

Evaluate f(x) = 2x^2 + 5x - 17 for f(2).

Back

f(2) = 7

Front

What is f(2) if f(x) = 4x?

Back

f(2) = 8

Front

Evaluate f(x) = x^2 for f(-8).

Back

f(-8) = 64

Front

What does the 'x' represent in f(x)?

Back

The 'x' represents the input value for the function.

Front

What is the output of a function?

Back

The output of a function is the result obtained after substituting the input value into the function's equation.

Front

If f(x) = x + 3, what is f(0)?

Back

f(0) = 3
