I just plugged them all in and D was the correct formula
Answer:
C P(v) = 2(v+7)
Step-by-step explanation:
To find P(v), we need to take the inverse of P^-1 (v)
y = 1/2 v-7
Exchange y and v
v = 1/2 y-7
Solve for y
Add 7 to each side
v+7 = 1/2 y -7+7
v+7 = 1/2y
Multiply each side by 2
2(v+7) = 1/2 y*2
2(v+7) = y
P(v) = 2(v+7)
