    sketching a function

    Hi, been a little while since ive done some math, and need help with a probably basic problem.

    It asks to sketch p=(1+x)^2 & p=1+2x for -1<x<1
    i would assume the first one is just like the parabola x^2 shifted to the left 1 unit. but with the restricted domain when i pop it in my graphic calc to check it looks bizarre. So, what does it look like?

    Thanks

    Hi, thanks thats great! could you remind me, what steps in order to get this?

    Also, there is a follow up question asking what range of values of v is the second function good within 5%? and you have to be accurate with a calc.. hmm
