f(x) = for x <1

**(x-1)^2**

for 1 <= x <= 4

**ax+b**find a and b so that fx is continuous for all x

for x <4

**sqrt (2x+1)**

so i guess i start evaluating some limit.

since the ax+b is define everywhere b/w x = 1 and x = 4, i guess i would use the third function f(x) = sqrt(2x+1) for limit goes to 4

f(x) = limit (x goes to 4) sqrt(s2+1) = 3

then i think i would let a = 3 ?

3x+b = ? what is y then?
