Describing Key Features of a Graph of a Polynomial Function:
Diano4ka-milaya [45]

<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.

<u>Graph:</u>
