Evaluating Functions and Function Notation

Front

Evaluate for f(-4) if f(x) = 2x - 10

Back

f(-4) = -2

Front

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

Back

Let x = 2

Front

Given that f(x)= 2x^2 + 5x - 17, find f(-1).

Back

f(-1) = -20

Front

Evaluate for f(-3) if f(x) = x^2 - 9

Back

f(-3) = 0

Front

g(x) = 3x + 1, find g(2).

Back

g(2) = 7

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 it mean to evaluate a function?

Back

To find the output of a function for a specific input value.

Front

If f(x) = x^2 + 3, what is f(0)?

Back

f(0) = 3

Front

If f(x) = 4x - 1, what is f(1)?

Back

f(1) = 3

Front

What is the domain of a function?

Back

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