h(x)=x 2 −1h, left parenthesis, x, right parenthesis, equals, x, squared, minus, 1 Over which interval does h hh have a negative

Semenov [28]

Answer:

(C)−3 ≤ x ≤ 1

Step-by-step explanation:

The average rate of change of function h over the interval $a \leq x\leq b$ , is given by this expression:

$\dfrac{h(b)-h(a)}{b-a}$

Given the function $h(x)=x^2-1$ on the interval:− 3 ≤ x ≤ 1

$h(1)=1^2-1=0\\h(-3)=(-3)^2-1=9-1=8$

The average rate of change:

$\dfrac{h(b)-h(a)}{b-a}=\dfrac{0-8}{1-(-3)}=\dfrac{-8}{4}=-2$

Therefore, the function has a negative average rate of change over the interval − 3 ≤ x ≤ 1.

CHECK:

(A)Average rate of change of h(x) over the interval − 3 ≤ x ≤ 5=2

(B)Average rate of change of h(x) over the interval 1 ≤ x ≤ 4=5

(D)Average rate of change of h(x) over the interval − 1 ≤ x ≤ 5=4

Write in form y=mx+b I will give brainiest to correct answer

Viktor [21]

Step-by-step explanation:

y=mx+b (m is the slope, b is the y-intercept)

To come with sope choose two points from the graph (6,20), (4,30)

Then

m=(Y2-Y1)/(X2-X1) =(4-6)/(30-20)=-1/5

b= 50 (y-intercept)

SO y=-1/5x-50

I hope this helps
