If f (x)=x 3 + 2x 2 - 3, what is f (-1)?

f(x)= x³+2x²-3

f(-1)= (-1)³+2(-1)²-3 = -1+2-3 = -4+2 = -2

f(-1)= -2 is the right answer.

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
