The answer to your question is f (g (x)) = x⁸ + 8x⁴ + 9

Step-by-step explanation:

Data

f (x) = x² + 2x - 6

g (x) = x⁴ + 3

(fg) (x)

Process

1. - Substitute g (x) in f (x)

f (g (x)) = (x⁴ + 3) ² + 2 (x⁴ + 3) - 6

2. - Simplify

f (g (x)) = x⁸ + 6x⁴ + 9 + 2x⁴ + 6 - 6

3. - Result

f (g (x)) = x⁸ + 8x⁴ + 9
