Is f(x)=(x^29x+14)/(x7) differentiable at x=7?
stuck between these two choices:
a. No, b/c f'(x)=0 at x=7
v. No, b/c f(x) is not continuous at x=7

Best ResponseYou've already chosen the best response.5Ask yourself whether 7 is even part of the domain of the function. Does your function have a nonvertical tangent line at \((7,f(7))\)?

Best ResponseYou've already chosen the best response.5You cant differentiate a function that has any sharp turns, breaks, etc that will make your function "non smooth"
