10. For the function y = x2, compute the average rate of change between x = 0 and x = 3. sorry wrong place!
Mr. Fantastic, is the reasoning correct?
Did he mean $\displaystyle x^2$ or 2x?
To answer this question if 2x, it should be 2.
D = R * T $\displaystyle \implies $ R = $\displaystyle \frac {D}{T}$
Let D = y, R = R, and T = x
Let x = 0 be the initial and x = 3 be final
Then R = $\displaystyle \frac {\Delta Y} {\Delta X}$
Then ...
R = $\displaystyle \frac {0 - 6}{0 - 3} $
R = $\displaystyle \frac {-6}{-3}$
R= 2
