Step-by-step explanation:
<u>Step 1: Define</u>
9.1p + 8.9r
p = 7
r = 8
<u>Step 2: Evaluate</u>
- Substitute: 9.1(7) + 8.9(8)
- Multiply: 63.7 + 71.2
- Add: 134.9
4 (1+ 6q) + 6q
4 + 24q +6q
4 + 30q
this is constant function because it doesn't contain variables
so, let's go
-2×2+7 = -4+7 = 3
so range is {3}
