Homework Statement
[tex]
u(x) =
\begin{cases}
\frac{3x+b}{4} & \text{if } x \geq 2 \\
\frac{(3-x)^n-a}{x-2} & \text{if } x < 2
\end{cases}
[/tex]
find the value of a and b for which the function is continuous at 2
The Attempt at a Solution
I tried to proof that lim(3x+b)/4 = lim (3-x)^n-a/x-2 = f(2)
that gives lim (3-x)^n-a/x-2= 6+b/4
But I have a problem with the limit when x< 2, I don't know how to solve it
Can u please help ?
