REVIEW Flashcard 3-2: Graphing Functions & Function Notation

Front

If f(x) = 3x - 9, find f(5).

Back

f(5) = 6

Front

Find the range of the function f(x) = 3x + 2 given the domain D: x = {-2, 0, 2}.

Back

Range: {-4, 2, 8}

Front

Back

f(-2) = -4

Front

For which value of x does f(x) = 2?

Back

x = -4

Front

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

Back

f(x) = 2x - 3

Front

What is a function?

Back

A function is a relation that assigns exactly one output for each input.

Front

What is function notation?

Back

Function notation is a way to denote functions using symbols like f(x) instead of y.

Front

What is the domain of a function?

Back

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

Front

What is the range of a function?

Back

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

Front

How do you find f(a) for a function f(x)?

Back

Substitute 'a' into the function in place of 'x'.
