Answer:
15x²
Step-by-step explanation:
Given
f(x) = 5x² , then
3f(x) = 3 × 5x² = 15x²
Answer:
f⁻¹(-2) = 3 and f⁻¹(1) = 0.
Step-by-step explanation:
By the definition of inverse functions:

From the table, note that f(3) = -2.
Then by definition, f⁻¹(-2) = 3.
Likewise, f(0) = 1.
Then by definition, f⁻¹(1) = 0.
Answer:
The circumference is 44 in.
Step-by-step explanation:
C = 2πr Use this equation to find the circumference
C = 2π(7) Multiply
C = 14π Multiply
C = 43.98 ≈ 44 in
