Which of the following represents the factorization of the polynomial function graphed below? (assume it has no constant factor.)

need answer asap!

B

Step-by-step explanation:

From the graph the roots are x = 1 and x = 3, hence

(x - 1) and (x - 3) are the factors of the polynomial and the polynomial is the product of the factors, that is

y = a(x - 1)(x - 3) ← a is a multiplier , here a = 1, thus

y = (x - 1)(x - 3) → B

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2
