Answer 1

Answer:

There is not enough info to complete this question. A function is needed so you can plug in -3 and 5

Step-by-step explanation:

Answer 2

The average rate of change from (-3,5) is 4.

What is average rate of change?

Average rate of change is defined as the ratio the change in y (output) to the change in x (input).

This question is incomplete there a function is needed

So, suppose f(x) = 2x²-5

Given that, x= -3 to x= 5

let a = -3 and b=5

F(a) = F(-3) = 2(-3)²-5 = 13

F(b) = F(5) = 2(5)² -5 = 45

∵ Average rate of change =  $\frac{F(b)-F(a)}{b-a}$

Substitue values

⇒  $\frac{F(5)-F(-3)}{5-(-3)}$

⇒  $\frac{F(5)-F(-3)}{5-(-3)}$

⇒ $\frac{45-13}{8}$

⇒ 32/8

⇒ 4

Thus, the average rate of change from (-3,5) is 4
