Need answer fast! the graph shows the daily revenue earned selling coupon cards in a fundraiser if the price is decreased by x dollars. which function can be used to determine the daily revenue if the price of a coupon card is decreased by x dollars?

From given graph we see that points forms a parabolic shape that means we can use quadratic model to find the equation whose formula is given by:

where (h,k) represents vertex.

From graph we see that vertex is (3,49).

Hence h=3 and k=49

Plug these values into above formula

we get:

Now we need to find the value of a, so we can plug any point say (5,45) then we get:

Plug value of a, h and k into above formula, we get:

which best matches with first choice

Hence final answer is

the answer is a
