## Answers ( )

h(t) = -9.8t² + 30t + 1.5

→ -64.54

The quadratic function, or a function of degree two, has three forms:

Vertex f(x) = a(x – h)2 + k, where (h, k) is the vertex, the highest or the lowest y value of the function.

Remember that a parabola is simply a graph of a quadratic function.

Answer:paul hit a baseball straight up into the air. The equation below describes the height of the ball (h), in meters, as a function of time (t) in seconds.

h(t) = -9.8t² + 30t + 1.5

What is the height of the ball after 3 seconds?

i keep getting -195.9
