Find the approxim
Δx and Δy are very small changes in x and y respectively.
As x changes from 2 to 2.002
x = 2
Δx = 2.002 – 2 = 0.002
The change Δy with change Δx is given by
Let us find
y = x-2
Substitute in (i)
Substitute values x = 2 and Δx = 0.002
⇒ Δy = -0.0005
As Δy is negative which implies y decreases.
Hence y decreases by 0.0005 as x goes from 2 to 2.002.
