Answer:

The average rate of change from x= -2 to x=0 is 0 (second option)

Step-by-step explanation:

Point A=(-2, 1)=(a, f(a))→a=-2, f(a)=1

Point B=(0, 1)=(b, f(b))→b=0, f(b)=1

Average rate of change from x=a to x=b:

r=(f(b)-f(a)) / (b-a)

Replacing the given values:

r=(1-1) / (0-(-2))

r=(0) / (0+2)

r=(0) / (2)

r=0

Help meeeee doooo thissss

Answer:

B:  x=-5  and x=4

Step-by-step explanation:

f(x)= x^2 + x -20

To find the zeros we replace f(x) with 0

0= x^2 + x -20

now we solve for x

LEts factor x^2 + x -20

sum is +1  and product is -20

5 * (-4)= -20

5 + (-4) = +1

x^2 + 5x - 4x - 20 = 0

(x^2 + 5x)+(- 4x - 20) = 0

x(x+5) -4 (x+5) = 0

(x-4)(x+5)=0

Set each factor =0 and solve for x

x- 4 =0 so x=4

x+5 =0 so x=-5

x=-5  and x=4
