Finding the rate of change is a fancy way of saying find the slope, so you are given p(x)=3x+4 and the interval [2, 2+h]

Just plug in 2 and 2+h for x using $\large \frac{f(b) - f(a)}{b-a} $ with the interval [a, b]:

$\large p(2) = 3(2)+4 =10$

and

$\large p(2+h)= 3(2+h) +4 = 10+3h $

Plugging it in:

$\Large \frac{(10+3h)-10}{(2+h)-2} $

I'm sure you could finish it from here

Thank ya lui c:

average rate of change = p(b) - p(a)

b - a a=2 and b=2+ℎ p(2+h)=3(2+h)+4=6+3h+4=10+3h p(2)=3(2)+4=6+4=10 (10+3h - 10

(2+h) - 2 = 3h ---- = 3 3
