Tim wrote y = -2(x+4)^2-13 in standard form as y = 2x^2+16x+45. Find his error. The standard form of y = -2(x+4)^2-13 is y = [ ]

Tim multiplied by [ ] instead of [ ]

needpoints sorry

Step-by-step explanation:

i think the correct option is the second option.

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).
