Homework Help: Find Values of c and f that make h continuous

  1. Sep 6, 2012 #1
    1. The problem statement, all variables and given/known data
    { 2x if x<1
    h(x)= { cx^2+d if 1<=x<=2
    { 4x if x>2

    2. Relevant equations

    3. 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.

    What did you get after you did that??

    After evaluating those 2 i get 2=c+d and 8=4c+d. I'm not quite sure what to do now

    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?
