Mrs. Barghi Function Notation and Evaluating Functions

Front

How would you write y = 2x - 3 in function notation?

Back

f(x) = 2x - 3

Front

If f(x) = 2x + 1, what would be your first step to find f(1)?

Back

Plug a 1 in for all the x's

Front

How do you read f(x)?

Back

f of x

Front

If h(x) = -5x + 7, evaluate h(2).

Back

-3

Front

For the function f(x) = -3(x-1), find f(0).

Back

3

Front

What is function notation?

Back

A way to represent functions using symbols, typically f(x), g(x), etc.

Front

What does f(2) mean in function notation?

Back

It means to evaluate the function f at x = 2.

Front

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

Back

9

Front

What is the domain of a function?

Back

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

Front

What is the range of a function?

Back

The set of all possible output values (y-values) for the function.
