Answer:

Rate = 1

Step-by-step explanation:

Given

g(x) = x + 7

Interval: (-2,4)

Required

Determine the average rate of change

This is calculated using:

Rate = \frac{g(b) - g(a)}{b-a}

Where:

(a,b) = (-2,4)

So, we have:

Rate = \frac{g(4) - g(-2)}{4-(-2)}

Rate = \frac{g(4) - g(-2)}{4+2}

Rate = \frac{g(4) - g(-2)}{6}

Calculate g(4) and g(-2)

g(4) = 4 + 7 = 11

g(-2) = -2 + 7 = 5

So:

Rate = \frac{11 - 5}{6}

Rate = \frac{6}{6}

Rate = 1

<em>Hence, the average rate of change is 1</em>
