Answer:
(-1, 19) and (3, -81)
Step-by-step explanation:
f(x) = 2x³ − 6x² − 27x
f'(x) = 6x² − 12x − 27
-9 = 6x² − 12x − 27
0 = 6x² − 12x − 18
0 = x² − 2x − 3
0 = (x + 1) (x − 3)
x = -1 or 3
f(-1) = 19
f(3) = -81
The points are (-1, 19) and (3, -81).
Answer:
You will do the Distributive Property first.
Step-by-step explanation:
You will do the Distributive Property first.
4(x - 3) = 9 <u>distribute the 4 into the x and -3.</u>
4x - 12 = 9 <u>add -12 to both sides.</u>
4x = 21 <u>divide 4 on both sides.</u>
x = 5.25 is your answer.
