Step-by-step explanation:
Step 1: Define
Identify
f(x) = 4x - 1
f(-2) is x = -2 for function f(x)
g(x) = 3x² - 2
g(6) is x = 6 for function g(x)
Step 2: Evaluate
f(-2)
- Substitute in x [Function f(x)]: f(-2) = 4(-2) - 1
- Multiply: f(-2) = -8 - 1
- Subtract: f(-2) = -9
g(6)
- Substitute in x [Function g(x)]: g(6) = 3(6)² - 2
- Exponents: g(6) = 3(36) - 2
- Multiply: g(6) = 108 - 2
- Subtract: g(6) = 106
