Homework Statement


{ 2x if x<1
h(x)= { cx^2+d if 1<=x<=2
{ 4x if x>2


Homework Equations





The Attempt at a Solution


It tried taking the limit of 2x and cx^2+d at x->1 (from both sides) and set them equal to each other. I did the same for 2 as well, but i got stuck after that.

Are you saying that you do not know how to solve two simple linear equations in two unknowns? Have you really never, ever, seen problems like that before?
