Answer:
1) h(t) = -5(t-3)^2
2) The ball reaches the highest point at 3 seconds.
Step-by-step explanation:
OK. So for this question, I recommend to rewite using vertex form since the answer is given in a more concise manner than using factored.
First Step:
h(t) = -5t^2+30t
= -5(t^2-6t)
= -5(t^2-6t+9)+45
= -5(t-3)^2+45
Second Step:
The vertex form reveals the vertex to be at (3, 45).
Therefore, the ball reaches the highest point at 3 seconds.

Look at the picture.
We have three rectangles. The formula of an area of a rectangle:

l - length
w - width
Rectangle I:

Rectangle II:

Rectangle III:

The area of number 4:

Substitute:

Answer:
F(x) = 2^x gives you (0,1)
G(x) =
+1 also gives you (0,1)
