Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 2x + 7
f(-3) is x = -3
<u>Step 2: Evaluate</u>
- Substitute: f(-3) = 2(-3) + 7
- Multiply: f(-3) = -6 + 7
- Add: f(-3) = 1
7/10 because when you make the denominators the same (10) you do same thing to the 3 making it a six and 7 is greater then 6
1st one is C and then the 2nd one is B
