Question

What is the rate of change from x = 0 to x = pi over 2?

Answer 1

The answer is b hope it helps

Answer 2

Answer with explanation:

→We have to rate of Change from , x=0 to , $x=\frac{\pi}{2}$.

→Points on the graph are , $(0,0),(\frac{\pi}{2},3),(\pi ,0),(\frac{-3\pi}{2},-3),(2\pi,0)$

Rate of Change between two points

      $=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

  $\text{When} , x_{1}=0,\text{then} , y_{1}=0,\text{ And When} , x_{2}=\frac{\pi}{2},\text{then} , y_{2}=3.\\\\ \text{Rate of Change}=\frac{3-0}{\frac{\pi}{2}-0}\\\\=\frac{3\times 2}{\pi}\\\\=\frac{6}{\pi}$
