devon wanted to know if x-3 is a factor of f(x)=x^3+x^2-10x+8. she applied the factor theorem and concluded that x-3 is not a factor of f(x), as shown in the following work.
f(-3)^3+(-3)^2-10(-3)+8=20
f(-3)=20, so the remainder is 20.
the remainder is 20, so x-3 is not a factor of f(x).
did devon make a mistake? if so, what was her mistake?
a. yes, devon evaluated f(-3) incorrectly.
b. no, devon did not make any mistakes.
c. yes, devon should have evaluated f(3)

C.

Step-by-step explanation:

To see if x-3 is a factor you plug in what makes it 0 which is 3.

Evaluating f at 3:

14

So the remainder of dividing f by (x-3) is actually 14.

The conclusion is still the same but the work Devon provided with her conclusion is wrong as she suppose to evaluate f(3) instead of f(-3).

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
