Look at exemplar above and use desmos to graph and identify the minimum for g (x) and compare it to r (x)

1 The quadratic functions r (x) and g (x) are given below.

X | r (x)

-4 | - 12

-3 | - 15

-2 | - 16

-1 | - 15

0 | - 12

1 | 7

q (x) = x² + 2x - 8

The function with the smaller minimum value is ...

1) q (x), and the value is - 9

2) q (x) and the value is - 1

3) r (x), and the value is - 16

4). r (x), and the value is - 2
