1-51.

The graph appears to be the linear function *y* = *x* + 2, with a hole at (1,3).

Just like the graph of *y* = *x* + 2, this function will go up (*y* →+∞) as we move to the right (*x* →∞)

Refer to the hint in part (a).

As the graph approaches the hole from the left (*x* → −1), what *y*-value does it approach?

Refer to the hint in part (c).
