Answer 2

Trying to figure this out.

Answer 3

what have you gotten so far?

Answer 4

None, I'm not sure where to start.

Answer 5

what does it mean to me a zero of a polynomial? or of any function?

Answer 6

try an example to make it mire concrete: P(x) = x+4, what value of x makes P(x)=0?

How would you describe that value?

Answer 7

*more concrete

Answer 8

x = 4, correct?

Answer 9

P(x) = 0 , but P(x) = x+4 sooo

x+4 = 0, when x=-4; therefore P(-4) = 0

in this case c = -4, which of the options can we eliminate now?

Answer 10

does P(0) = -4?

does x=-(-4) produce a zero in this poly?

is -4 a factor of the poly? whatever that means ...

is -4 the x intercept of the graph of this poly?
