Answer 1

Answer:

78

Step-by-step explanation:

You use the formula

$\frac{f(b) - f(a)}{b - a}$

with a=2 and b=5 plug it in to the formula

$\frac{f(5) - f(2)}{5 - 2}$

find the values

$f(5) = {3}^{5} + 4 = 247$

$f(2) = {3}^{2 } + 4 = 13$

put it all together

$\frac{247 - 13}{5 - 2} = \frac{234}{3} = 78$
