Question

Please help me, this is my last day for everything! :(

Answer 1

B) y=15x^2+18 i hope it help you.

Answer 2

y = 15x^2 + 18

Explanation:

Trial and error by plugging in 10 in every equation and see if the answer is close to the one in the graph.

y = 450(10) - 600 = 3900 too big

y = 15(10)^2 + 18 = 1518 between 1400 and 1600 so this is the answer

y = 100(10) - 200 = 800 too small

y = 3(10) + 10 = 40 too small
