Answer:

Option B

Step-by-step explanation:

Average rate of change of a function 'f' in the interval x = a and x = b is given by,

Average rate of change of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]

Given function is,

g(x) = [tex]\frac{5}{x-1}+2[/tex]

We have to calculate the rate of change in the interval [-4, 3],

Average rate of change = [tex]\frac{g(3)-g(-4)}{3-(-4)}[/tex]

g(3) = [tex]\frac{5}{3-1}+1[/tex]

       = 2.5 + 1

       = 3.5

g(-4) = [tex]\frac{5}{-4-1}+1[/tex]

       = -1 + 1

       = 0

Average rate of change = [tex]\frac{3.5-0}{3+4}[/tex]

                                        = [tex]\frac{3.5}{7}[/tex]

                                        = [tex]\frac{1}{2}[/tex]

Therefore, Option B will be the answer.
