Question

Graph each function.

1. y = x^2 + 5

Which numbers should I choose as the x-values?

Answer 1

Don't pick numbers which yield a large y value, and thus hard to plot
I would pick
x = ±1, ±2, ±3

that gives you 6 points, and a good indicator of the graph.

Answer 2

X
-2
-1
0
1
2
3
4

Answer 3

Include x = 0 for sure :)
