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

Answer:
[tex]\frac{6}{\pi}[/tex]
Step-by-step explanation:
Rate of change is the change in y divided by change is x
** Change in y = [tex]3-0\\=3[/tex]
** Change in x = [tex]\frac{\pi}{2}-0\\=\frac{\pi}{2}[/tex]
Thus rate of change = [tex]\frac{3}{\frac{\pi}{2}}\\=3*\frac{2}{\pi}\\=\frac{6}{\pi}[/tex]
Last answer choice is right.
