Identifying Key Aspects of Quadratic Functions Place each of the key aspects under the function it describes.

h(x) = (x - 1)
g(x) = -(x + 1)(x - 1)
decreasing over (-0, 1)
increasing over (-0, 0)

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
