Question

This is an online ACT prep guide problem that I’m having trouble on.Below, is the answer options to this problem.A. -4B. 1C. 6D. The limit does not exist.

Answer 1

Step 1

Given; A graph

Required; To find f(-4)

Step 2

The graph at x=-4 has a removable discontinuity. Therefore we can then conclude that f(-4) is undefined.

Hence, f(-4) is undefined

A removable discontinuity is a point on the graph that is undefined or does not fit into the rest of the graph.
