The function below represents the height of an object when it is dropped from a height of 144 ft, where x is the number of seconds after release. What is the average speed (or average rate of change) during the first 2 seconds after release? f(x)=-16x^2+144

Group of answer choices

Rising at a rate of 32 feet per second

Falling at a rate of 144 feet per second

Rising at a rate of 80 feet per second

Falling at a rate of 32 feet per second

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

8(1/6)

step-by-step explain:

49/6= 48

8 (1/6)

i think the answer is b x = 1, y = 35/2
