Evaluating Function

What is the value of f(10)?

Hint: When x is 10, what is y?

f(x)=x+3

f(-5) = ?

• -2

• -1

• -8

• 7

f(x)=2x+2

for x = 4

• 6

• -8

• 10

• 0

Evaluate f(t)=-2t²+ 1 for f(-3)

• 19
  

• 37

• -17

• -11

Evaluate f(t)=-2t²+ 1 for f(2)

• 9
  

• 17

• -17

• -7

g(x) = 5 - 6x
Find g(-5)

• g(-5) = -25

• g(-5) = 6

• g(-5) = 4

• g(-5) = 35

f(x) = 3x² - 11
Find f(-5)

• f(-5) = 64

• f(-5) = -86

• f(-5) = 214

• f(-5) = -7

Evaluate r(3)

• r(3) = 16

• r(3) = 12

• r(3) = 13

• r(3) = 0

Let g(x)=9x+24, find g(3).

• 3

• 33

• 51

• -2.66

If a question asks you to find f(2), what does that mean?

• Let x = 2

• Let y = 2
