Question

What is the rate of change between the interval of x = 0 and x = pi over two?
graph below

Answer 1

2 over pi
pi over two
pi over four
four over pi

Answer 2

\[\large \frac{f(b) - f(a)}{b - a}\]

So lets have a = 0 and b = pi/2

So when x = 0..what does y equal/

and when x = pi/2 what does y equal?

Answer 3

0,3 and pi/2,5

Answer 4

Right...so

\[\large \frac{f(b) - f(a)}{b - a} \rightarrow \frac{5 - 3}{\frac{\pi}{2} - 0} \rightarrow \frac{2}{\frac{\pi}{2}} \rightarrow 2 \times \frac{2}{\pi} \rightarrow \frac{4}{\pi}\]

Answer 5

so it would be d?

Answer 6

D would be the correct answer...but do you see why?

Answer 7

Yes I think I get it now. Thank you so much! :)
