1.9975

Step-by-step explanation:

The computation of the linear approximation of the given function is shown below:

L(x) = 2 - 1 Γ· 4(x)

As we are looking for √3.9

So here

x = 0.1

So

= 4 - 0.1

= 3.9

Now

L(0.1) = f(3.9) = 2 - (0.1 Γ· 4)

= 1.975

now

substitute the x = 0.01

Then

L(0.01) = f(3.99) = 2 - (0.01 Γ· 4)

= 1.9975

We simply applied the above equations
