<u>Step 1: Define</u>
<em>Identify</em>
f(x) = x - 7
g(x) = x²
<u>Step 2: Find f(g(4))</u>
- Substitute in <em>x</em> [Function g(x)]: g(4) = 4²
- Evaluate exponents: g(4) = 16
- Substitute in <em>x</em> [Function f(x)]: f(g(4)) = 16 - 7
- Subtract: f(g(4)) = 9
Answer:
9
Step-by-step explanation:
f(x) = x − 7
g(x) = x^2
Find g(4) = 4^2 = 16
Then find f(g(4)) = f(16) = 16 -7 = 9
