Let f be the piecewise defined function given by f(x)=ax+b x≤2. 2-x^2 2<x. Find a and b so that f is differentiable at x=2.
Nevermind. I found that one out too.
But this one is impossible :/
Find the tangent line to the graph of f(x)=1/(x+4) at x=-3.
You will need to use the definition of the derivative to find the slope of the tangent line.
Put your answer in the form y=mx+b.
