What is the value of g(f(x)) when x = -2 if f(x) = x³
and g(x) =
2x+1
when x < 0
x²-1
when x>0

Answer:
g(f(-2)) = -15
Step-by-step explanation:
• f(x) = x³
Then
f(-2) = (-2)³ = -8
• When x = -2 → g(f(x)) = g(f(-2)) = g(-8)
Since -8 ≤ 0 then g(-8) = 2×(-8) + 1 = -16 + 1 = -15
Conclusion:
g(f(-2)) = -15
