ANSWER
C) f(3) − f(1) = f(6) − f(4)
EXPLANATION
The given function is f(x)=3x
f(3)=3(3)=9
f(1)=3(1)=3
f(3)-f(1)=9-3=6
Also,
f(6)=3(6)=18
f(4)=3(4)=12
f(6)-f(4)=18-12=6
Therefore the correct choice is
C) f(3) − f(1) = f(6) − f(4)

<u>Step 1: Define</u>
<em>Identify</em>
f(x) = -2x + 7
g(x) = x² - 2
<u>Step 2: Find f(g(3))</u>
- Substitute in <em>x</em> [Function g(x)]: g(3) = 3² - 2
- Evaluate exponents: g(3) = 9 - 2
- Subtract: g(3) = 7
- Substitute in g(3) [Function f(x)]: f(g(3)) = -2(7) + 7
- Multiply: f(g(3)) = -14 + 7
- Add: f(g(3)) = -7
