Evaluating Functions

Front

Evaluate y = 7x when x = -5

Back

y = 7(-5) = -35

Front

For what value of x does f(x) = -2?

Back

x = -5

Front

Evaluate the function for the given value: f(x) = 6x when x = 5

Back

f(5) = 6(5) = 30

Front

Evaluate the function for the given value: f(x) = 3x + 12 when x = 17

Back

f(17) = 3(17) + 12 = 63

Front

What is the definition of a function?

Back

A function is a relation where every input has only ONE output.

Front

Evaluate y = 2x + 4 when x = 3

Back

y = 2(3) + 4 = 10

Front

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

Back

The range is all non-negative real numbers [0, ∞).

Front

Evaluate f(x) = x^2 - 4 when x = 2

Back

f(2) = 2^2 - 4 = 0

Front

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

Back

The domain is all real numbers except x = 0.

Front

Evaluate f(x) = 5x - 3 when x = -1

Back

f(-1) = 5(-1) - 3 = -8
