Question

Evaluate f(-3) where f(x) is the piecewise function

Answer 1

Answer:
`f(-3) = 4`

At the point -3, two horizontal lines meet, at two different y levels. However, one of these horizontal lines has a hole, while the other is a point. The line with the point is where the graph is at that x value, while the hole represents that all the points on that horizontal line are valid EXEPT for that one point. The point reaches a y value of 4, therefore, f(-3) = 4.
