Determine the x-intercepts and the x-coordinate of the vertex of the graph that represents each equation.
equation
x-intercepts x-coordinate of the vertex
y = x(x - 2)
y = (x - D(x + 5)
y = -5x(3 - x)

answer: -8.2562234e+13

idk lol xd

step-by-step explanation:

ez do it yourself lazy

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).
