Plz help me with this

Answer 1

Answer:   b)  (x - 2)(x + 1)(x + 3)

Step-by-step explanation:

Look at the graph to find the x-intercepts (where the graph crosses the x-axis).

x = 2      x = -1    and      x = -3

Now rearrange each of those equation so they are equal to zero:

x - 2 = 0    x + 1 = 0  and   x + 3 = 0

Next, combine them (using multiplication):

(x - 2) (x + 1) (x + 3) = 0

Lastly, evaluate the sign of the a-value (coefficient of the polynomial):

Since the right side of the graph goes to POSITIVE infinity, then the a-value is positive.
