|dw:1351525495611:dw|

2. ksaimouli

this is deferentiable or not how can i say /

@Callisto

4. ksaimouli

how can i figure out whether this function is differentiable or not

5. zepp

This function is differentiable only at where this function exists

6. zepp

The derivative of this function would be $\large \frac{d}{dx}(x^{\frac{2}{5}})=\frac{2}{5x^{\frac{3}{5}}}$

7. zepp

Differentiable from 0 to $$+\infty$$

8. zepp

Wait, I'm not sure :/

9. Callisto

Hmm... A function is differentiable when the left hand limit = right hand limit as x-> c, I think? Of course, that function must be continuous. Perhaps you can read this: http://www.math.wfu.edu/tutorials/Math111/ContinuityandDifferentiability.pdf Check the part differentiability.

nope can any one explain how to graph without taking points

11. ksaimouli

this one has corner so not differentiated
