Answer:8. h(t) = -6 ((t-6) -3.7)^2 + 82.14 +20

9.b) At about 7.4 seconds.

Yes, on #7 the function is located 3 places to the right and 2.5 up, but that's just counting the tiny squares. If you look at the number and problem, on #8, you can't add +2.5, because the rocket wasn't on a platform 2.5 feet high. Remember that outside the parentheses + means up and - means down. So add + 20(ft).    but for question 8, and 9. b), try these answers. please mark brainlest
