Subtract 350 from both sides then divide both sides by 25.
(c-350)/25 = h
The radius of the new sphere is 9
The new SA should be 1017.36 in
New volume should be 3052.08in^3
<u>End behavior: </u>
The parent function is: f(x) = x³, which starts (from the left side) at -∞ and ends (on the right side) at +∞.
<u>Zeroes:</u>
f(x) = x³ + 2x² - 8x
0 = x³ + 2x² - 8x
0 = x(x² + 2x - 8)
0 = x(x + 4)(x - 2)
0 = x 0 = x + 4 0 = x - 2
x = 0 x = -4 x = 2
<u>Intervals:</u>
Put the zeroes in order: -4, 0, 2
since f(x) is increasing from the left then the interval from -4 to 0 is positive and the interval from 0 to 2 is negative.

To find the slope, use the equation slope=rise/run.
rise= 7-(-1) = 8
run = 4-1 = 3
The slope is 8/3
The answer would be 2. You have to do multiplication first.
