Question

Help with differentiation Please! Problem Below

Answer 1

If\[f(x) = x^2, x \le1\] and \[f(x)=2x, x>1\] is f differentiable at 1?

Answer 2

wait though, it isn't continuous at 1

Answer 3

your write cuz it looks like this

IT is continuous but not differentable at x=1

sorry if i confused u before

Answer 4

that isnt continuous

Answer 5

also why is it not differentiable

Answer 6

Limits:
usually we look at a specific value when the graph approaches a number that we are after. A limit won't exist when we get different solutions from above and below graph (See my picture)
