Answer: Option B
[3, 5]
Step-by-step explanation:
The function g(x) is a line of slope m = 4. Therefore, its rate of change is constant and equal to 4.
The rate of change of the function f(x) in the interval [tex][x_1, x_2][/tex] is calculated with the following formula
[tex]m =\frac{y_2-y_1}{x_2 - x_1}[/tex]
Note that the rate of change of the function increases as x increases.
For example
For [-1, 0]
[tex]m =\frac{4-3.5}{0 - (-1)}[/tex]
[tex]m =\frac{1}{2}[/tex]
[tex]\frac{1}{2}<4[/tex]
For [0, 2]
[tex]m =\frac{7-4}{2 - 0}[/tex]
[tex]m =\frac{3}{2}[/tex]
[tex]\frac{3}{2}<4[/tex]
For [1, 3]
[tex]m =\frac{11-5}{3-1}[/tex]
[tex]m =3[/tex]
[tex]3<4[/tex]
For [3, 5]
[tex]m =\frac{35-11}{5-3}[/tex]
[tex]m =12[/tex]
[tex]12>4[/tex]
