When given an absolute value function f(x) we are asked to find lim as x->a of f(x). The standard form for an absolute value function is f(x)=a|bx+c|+d. We begin by computing the limits from the left and right of a. In other words, as the graph approaches f(a) from the left, what y-value is it? Repeat for right of a
