A company is selling bubble gum. The function g(x)=3x+4 tells the company how much to charge if someone buys x packages of bubble gum. Find g(8) and tell what it means within the context of the problem.

• g(8)=8. This means that after 8 packages of gum, the company makes $8.

• g(8)=42. This means that 8 packages of gum costs $42.

• g(8)=28. This means that 8 packages of gum costs $28.

• g(8)=24. This means that 8 packages of gum costs $24.

If f(x) = 2x² + 5x - 3, evaluate f(-1).

• f(-1) = -6

• f(-1) = 1

• f(-1) = -10

• f(-1) = -1

f(x)=4x+5

f(4)=

• 21

• -11

• -31

• 25
