Answer:

0 and 2

Step-by-step explanation:

f(x) = g(x) will be the input or x value at which f and g have the same output or y value. Look in the table where two numbers repeat right next to each other.

−1 −7/2 −9/2


0 −3 −3


1 −2 −3/2


2 0 0


3 4 3/2


4 12 3


5 28 9/2

There are two solutions to f(x) = g(x) which are x=0 and x=2.

Joseph jumped off of a cliff into the ocean in Miami while vacationing with some friends. His height as a function of time is gi
Aneli [31]

Answer:

Step-by-step explanation:

I think the missing equation in your question is: h(t) = -16 t^{2} + 16t + 480

Here is my answer:

As we know that the vertex form of a parabola, y=a(x-h)^{2} + k where(h,k) is the vertex

h(t) = -16 t^{2} + 16t + 480

= -16 (t^{2} -t) + 480  

= -16 (t-\frac{1}{2}) ^{2} + 484

So the vertex is (\frac{1}{2} , 484)

a. It take for Joseph \frac{1}{2} second to reach his maximum height

b. The highest point that Joseph reached is the vertex of the function, it is 484 ft

c. Joseph hit the water after how many seconds?

<=> h(t) = 0

<=>  -16 t^{2} + 16t + 480  = 0

<=> t = \frac{192}{32} second = 6 sec

Hope it will find you well
