Pl answer which expression below gives the average rate of change of k on -3 ≤ x ≤ 5 ?

ave rate of change = k(5) - k(-3)

                                   5+3

Step-by-step explanation:

To find the average rate of change

ave rate of change = f(x2) - f(x1)

                                   x2-x1

We know that x2 = 5 and x1 = -3

ave rate of change = k(5) - k(-3)

                                   5--3

ave rate of change = k(5) - k(-3)

                                   5+3

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
