The graph of f^-1 (x) is
called the inverse function of f (x). The relationship between the two is that the
point (x,y) is on the graph of f (x) if and only if the point (y,x) is on the
graph of f^-1 (x).
This means that if the point
(2, 7) is on f (x), therefore the point (7, 2) is on f^-1 (x).

Answer:
= - 4 cm/s
Step-by-step explanation:
Let us revise the chain rule
If = a and 
= b, then
= ÷ = 
∵ y = x² + 1
- Use the differentiation to find
∴ = 2x
∵ x = -1
- Substitute x by -1 in
∴ = 2(-1)
∴ = -2
∵ = ×
∵ = 2 cm/s
∴ = (-2) × (2)
∴ = - 4 cm/s
