Mr. Wilson opened a bakery and a juice bar in his neighborhood. The functions below represent the profit, in dollars, earned fro
zavuch27 [327]

Answer:

The answer is given below

Step-by-step explanation:

The question is not complete, because the function for the profit is not given but I can show you how to calculate this.

Since Mr. Wilson has a bakery and a juice bar, his total profit earned in t months would be the sum of profit from the bakery with the profit from the juice bar within t months.

Let us assume that the profit from the bakery in t months is given by:

B(t) = 2t³

while the profit from the juice bar in t months is given by:

J(t) = 2.3^t-2

Therefore the total profit is given by:

P(t) = B(t) - J(t) = 2t^3+2.3^t-2

Answer:

Step-by-step explanation:

f(x)=-4x+2

g(x)=x²+1

(gof)(x)=g(f(x))=g(-4x+2)=(-4x+2)²+2=16x²-16x+4+2=16x²-16x+6

(gof)(3)=16(3)²-16(3)+6=144-48+6=150-48=102
