Answer: W(x + 4) = x + 8
<u>Step-by-step explanation:</u>
I am assuming the "t" is supposed to be an addition sign "+"
w(x + 4) means to replace all of the x's in the given function with x + 4
W(x) = x + 4
W(x + 4) = (x + 4) + 4
= x + 8
Answer:
Therefore the maximum height that the reach is 49 feet after 1.75 seconds.
Step-by-step explanation:
Given that,
A ball is thrown vertically upward. After t seconds its height is given by the function
where h is height in feet.
Maximum value:
Given function f(x)= at²+bt+c.
- Find the value
- Putting
in the given function. - The maximum value of the given function is
.
Here a= -16 , b=56 and c=0
The ball attains its maximum height when 
s.
Putting the value of t in the given function
=49 feet
Therefore the maximum height that the reach is 49 feet after 1.75 seconds.
Count from the origin to the center of the parabola. You will notice that there are 4 units.
So, the axis of symmetry is the line x = 4. The equation x = 4 cuts the parabola exactly in half.
