Homework Statement
y=
y= {1+3ax+2x^2} if x is < or = 1
{mx+a} if x>0
what values for m and a make x continuous and differentiable at 1?
Homework Equations
n/a
The Attempt at a Solution
i solved for when x=1.
i got 3+3a.
this is also the right hand limit. i kow you have to set the two limits equal for it to be continuous. so i got 3a+3=m+a. m=2a+3.
but honestly i don't know where to go from there. i know that i have to take the derivative of those two equations too. but i don't even kow what to say too many variables!
thanks in advance!
