Which expression best describes how Kamar sees the
pattern growing? (n is the number of blue stars, it is also
the number of the figure in the pattern)
O 1+n+n
O 1 + 2n + 3nt...
0 1+n?

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values

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).
