Evaluating Functions Do Now

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

• 0
• -3
• 3
• -1

Evaluate f(-5) if f(x) = -2x - 12

• -22
• -2
• -19
• -5

If f(x) = 7, what is the value of x?

f(x) = 3x+1

• 2

• 3

• 22

• 0

• 1

• -5

• -3

Let's Try it:

If the input is -3, determine the corresponding output.

• f(x) = -2

• y = -2

• f(x) = 10

• y =10

Find f(x) if x=-2.

• f(x)=9

• f(x)=-15

• f(x)=-9

• f(x)=21

f(5) = ?

• 25

• 125

• 5

• 10
