If I know that f(2) = 4, what is another way I can write my answer?

• (4, 2)

• (2, 4)

• f = 2

• f = 1/2

What is f(8)? 

• 8

• 0

• 3

• -2

Evaluate f(2).

• f(2) = 5

• f(2) = 12

• f(2) = 10

• f(2) = 0.5

Evaluate f(-3)

• f(-3) = -3

• f(-3) = 0

• f(-3) = 2

• not enough information to give an answer

f(x)=4x+5
f(4)=

• 21

• -1/4

• 16x + 5

• 16x + 20

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.
