find the value of c so that (x+1) is a factor of the polynomial p(x) p(x)=cx^4+2x^2-13

c = 11

Step-by-step explanation:

If (x + 1) is a factor of p(x) then x = - 1 is a root and

p(- 1) = 0, hence

c + 2(- 1)² - 13 = 0

c + 2 - 13 = 0

c - 11 = 0 ( add 11 to both sides )

c = 11

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
