Been a while since I've done this, can someone make sure I did it right?
Emily is throwing a ball into the air and catching it. The height of Emily’s ball is modeled by the function h(t) = –16t^2 + 48t + 15. What is the maximum height of Emily's ball?

Find vertex of function using -b/2a
-48/2(-16) = -48/-32 = 1.5
Plug in 1.5 for t
-16(1.5)^2 + 48(1.5) + 15
-36 + 72 + 15
51 ft
