question

Complete the table.

f(q) = q² + 10
q	f(q)
^–1
0

2

solution

The first q-value in the table is ^–1. Evaluate f(q) = q² + 10 for q = ^–1.

f(q)	=	q² + 10

	=	(^–1)² + 10	Plug in q = ^–1

	=	1 + 10	Square

	=	11	Add

When q = ^–1, f(q) = 11. Complete the first row of the table.

f(q) = q² + 10
q	f(q)
^–1	11
0	?
1	?
2	?

Next, evaluate f(q) = q² + 10 for q = 0.

f(q)	=	q² + 10

	=	0² + 10	Plug in q = 0

	=	0 + 10	Square

	=	10	Add

When q = 0, f(q) = 10. Complete the second row of the table.

f(q) = q² + 10
q	f(q)
^–1	11
0	10
1	?
2	?

Complete the rest of the table the same way.

f(q) = q² + 10
q	f(q)
^–1	11
0	10
1	11
2	14
