Answer 4

lets start with number 8

Answer 5

for 8 i got false

Answer 6

but m not 100%

Answer 7

lets look at a theorem.
"Given a nonzero polynomial P(x), if P(a) = 0 then (x-a) is a factor of P(x)"

so here we want to check P(-3) ,
if P(-3) =0 , then ( x- (-3)) is a factor of P(x)

note that ( x - (-3)) = x + 3

thats why I picked P(-3)

Answer 8

ok sure

Answer 9

P(-3) = -144 , and since P(-3) is not equal to zero, therefore ( x - (-3)) is not a factor of P(x) , or (x +3) which is equivalent to ( x - (-3))

Answer 10

so you are correct

Answer 11

Ok good i did learn something :D

Answer 12

so can we look at 9 please

Answer 13

if f(c) = 0, that is an x intercept
