H(t)=(t+3)^2+5

over which interval does h have a negative average rate of change?

choose 1

(choice a)

−2≤t≤0

(choice b)

1≤t≤4

(choice c)

−4≤t≤−3

(choice d)

−3≤t≤4

Option C. −4≤t≤−3

Step-by-step explanation:

we have

This is the equation of a vertical parabola written in vertex form

The parabola open upward (the leading coefficient is positive)

The vertex is a minimum

The vertex is the point (-3,5)

The function is increasing in the interval [-3,∞)

The function is decreasing in the interval (-∞,-3]

The function will have a negative average rate when the function will be decreasing

therefore

the answer is option C

its not b

step-by-step explanation:

d

because parallelagram have all 4 angels the same size dependeing and a rectangle and square are oth parallelogram
