Step-by-step explanation:
y=7x-10
Answer: $6197.77 would be the right answer
hope it helps :]
I wanna say 10 or ether -10 since if it was subtracted from 2 then it would equal -8
Ok, so we see in
y=a(x-h)^2+k
vertex is (h,k)
vertex is highest or lowest point
on one side, it goes up and other side it goes down
if a is positive, then it goes down then up
if a is negative, it goes up then down
we see
f(x)=2(x+3)^2+2
2 is positive
goes down then up
vertex is (-3,2)
so decreases from -infinity to -3 or ininterval
(-infinity,-3)
answer is first option
Divide 3 on the numerator and denominator.
Hoped this helped.
