Answer: D) $y=-5(x-5)^2+1125$

Step-by-step explanation:

Let x be the number of $2 increases in price and y be the revenue.

By using the given table , lets check all the options

A) $y=(x+5)^2-1125$

For x=1, y=1045

$y=(1+5)^2-1125=36-1125=-1089\\\\But\ 1045\neq-1089$

B) $y=(x-5)^2+1125$

For x=1, y=1045

$y=(1-5)^2+1125=14+1125=1139\\\But\ 1045\neq1139$

C) $y=-5(x+5)^2-1125$

$y=-5(1+5)^2-1125=-5(36)-1125=-1305\\\\But\ 1045\neq-1305$

D) $y=-5(x-5)^2+1125$

$y=-5(1-5)^2+1125=-5(16)+1125=1045$

Hence, this is the quadratic equation that models the data.
