In Algebra, we learn about many types of functions. These functions vary from simple to complex. Think about the different types of functions we’ve explored so far (linear, quadratic, and exponential). What features do they share, and how are they unique?

s

step-by-step explanation:

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).

the answer is b.
