Finding Limits

Find the limit of f(x) as x approaches 1 from the right.
f(x) = 2     if  x<1
         x+3     if 1 less than or equal to x less than or equal to 3
           6       if x>3

Re: Finding Limits

if we're approaching from the right, then we are using the middle condition, that 1 > x <= 3, since as x approaches 1, it will always be greater than 1

and lim(x->1) x+3 = 4
