Answer:
f(f(x)) = 27
+ 18x² + 4
Step-by-step explanation:
To find f(f(x)) substitute x = f(x) into f(x) , that is
f(3x² + 1)
= 3(3x² + 1)² + 1 ← expand parenthesis using FOIL
= 3(9 + 6x² + 1) + 1 ← distribute parenthesis by 3
= 27 + 18x² + 3 + 1 ← collect like terms
= 27 + 18x² + 4
0.433 is rounded to the hundredths already, so to round it to the nearest tenths, just remove the last number.
Your answer is going to be 0.43
