Answer:
See below...
Step-by-step explanation:
For a function whose formula is in this pattern:

Amplitude: 
Period: 
Phase Shift: C
In this question, 
Amplitude: 4
Period: 
Phase Shift: 
There is no vertical shift, so the midline is the x-axis whose equation is y = 0.
Also, because there is no vertical shift, the maximum is 4 and the minimum is -4.
The graph is attached.
Answer:
(8.5)
Step-by-step explanation:
Just add the 2 numbers
Answer:
x=4,-2/3
Step-by-step explanation:
To solve for x, we first subtract 8 from both sides.
So 3x^2-10x-8=0
Using the quadratic formula, we get
X=(10+sqrt(100+96))/6 or x = (10-sqrt(100+96))/6
So x=(10+14)/6 or x=(10-14)/6
So x=4 or x=-2/3.
