√17
√12
<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.

Hello from MrBillDoesMath!
Answer:
1/5
Discussion:
$12000 * (1/5) = $2400
$12000 * ( 1/10) = $1200
As 2400 > 1200, (1/5) is the best way to go
Thank you,
MrB
C, just consider when x=0,find the y
Draw (or do whatever) 13 in tens and ones [1 ten block ,3 ones blocks] then draw 7 in ones. then show the breaking apart of the tens block then subtract it by 7.
