Question

If f(x) = 2/3x^2 +8 , what is the value of f(6)?

Answer 1

f(6)= 72

Explanation:

f(6)= 72

to evaluate:

substitute x = 6 into

f(x)f(6)= 23 × (6) 2 + (8×6)×x = 231 × 3612+ 48

Answer 2

Explanation:

Step 1: Define

f(x) = 2/3x² + 8

f(6) is x = 6

Step 2: Evaluate

1. Substitute in x: f(6) = 2/3(6)² + 8
2. Exponents: f(6) = 2/3(36) + 8
3. Multiply: f(6) = 24 + 8
4. Add: f(6) = 32
