Am • an = am + n, where a is a real number and m and n are integers use the product of powers property to simplify the expression –2x3y4x2y3.

correct

-2x^5y^7

Step-by-step explanation:

linear

step-by-step explanation:

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
