For this question: I'm having a lot of trouble figuring out f(0). Can anyone help? I know that f'(-0.5)=4 which means that f(4)=-0.5 and I know that f(-0.5)=2 which means that f'(2)=-0.5, right? But I don't know how to relate this to tangent line approximation and find f(0). Can anyone explain this to me? Thanks!
