Function Notation Practice

Front

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

Back

f(x) = 2x - 3

Front

Given f(x)=2x+1, find x if f(x)=16.

Back

x = 15/2

Front

What is the definition of a FUNCTION?

Back

Each input is paired with exactly one output.

Front

Given the function f(x)=2x+1, find f(4).

Back

f(4) = 9

Front

What is f(8) if f(x) = 2x - 18?

Back

f(8) = -2

Front

What does f(x) represent in function notation?

Back

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

Front

If f(x) = 3x + 4, what is f(0)?

Back

f(0) = 4

Front

What is the range of the function f(x) = x^2?

Back

The range is all non-negative real numbers.

Front

If f(x) = x - 5, what is f(10)?

Back

f(10) = 5

Front

What is the domain of the function f(x) = 1/x?

Back

The domain is all real numbers except x = 0.
