Back

-2

Front

Determine if the relation is a function: { (1, 2), (1, 3), (2, 4) }

Back

Not a Function

Front

Find (f - g)(x) if f(x) = 5x - 7 and g(x) = 3x + 10.

Back

2x - 17

Front

Are the functions f(x) = 2x + 3 and g(x) = x - 3 inverses of each other?

Back

False

Front

Solve for x if f(x) = -4x - 10 and f(x) = 10.

Front

What is the definition of a function?

Back

A relation where each input has exactly one output.

Front

What is the slope of the line represented by the function f(x) = -4x - 5?

Back

-4

Front

What does it mean for two functions to be inverses?

Back

How do you find the difference of two functions, (f - g)(x)?

Back

Subtract the output of g(x) from f(x).
