Is x - 8 a factor of the function f(x) = -2x3 + 17x2 - 64? Explain.
2 answers:
we know that
If
is a factor of the function 
then
is a root of the function f(x)
therefore
For
the value of the function must be zero
Verify
Substitute the value of
in the function





therefore
<u>the answer is</u>
Yes,
is a factor of the function f(x)
X-8=0
x=8
f(8)=-2(8)^3 +17(8)^2 - 64
=-2(512) + 17(64) - 64
= -1024+1088-64
= -1024 -64+1088
= -1088+1088
=0
so, x-8 is a factor of the function f(x) = -2x3 +17x2 - 64
hope this helps!!!!!! ^_^_^

16.25
Step-by-step explanation: <em><u>To The Nearest Hundredth</u></em>
(-1, 2), (3, 1)
<u>√17</u>
(3, 1), (7, 2)
<u>√17</u>
(3, 1), (7, 2)
