Question

Use the graph below to answer the question that follows:

Answer 1

D is the answer............................

Answer 2

Answer:

the correct answer is option D.

Step-by-step explanation:

average rate of change in the graph in interval x = 0 and x = pi/2

when we look into the graph between interval x = 0 and x = pi/2

we can see that on y - axis  

at  x = 0                value of   y = 3   and

at  x = π/2             value of   y = 5  

rate of change = $\frac{change\ in y-axis}{change\ in\ x-axis}$

                        = $\dfrac{y_2-y_1}{x_2- x_1}$

                        =$\dfrac{5-3}{\frac{\pi}{4} - 0}$

                        = 4/π

hence, the correct answer comes out to be 4/π

hence, the correct answer is option D.
