The functions below represent the amounts of water released from two reservoirs over x weeks.

f(x) = 7x – 8x – 2

g(x) = 4x2 + 3x + 15

which of the following shows the difference in the amounts of water released, h(x) = f(x) – g(x)?

a) h(x) = 7x + 4x2 + 11x – 17

b) h(x) = 7x + 4x2

c) h(x) = 7x + 4x2 – 11x + 17

d) h(x) = 7x – 4x2 – 11x – 17 < this is the answer

f is the midpoint of

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
