Find the linearization L(x) of the function at a. f(x) = sqrt x , a = 4
L(x) = ?

Step-by-step explanation:

Linearization

It consists in finding a linear approximate function around certain point x=a of a non linear function. The equation used to linearize a function f is given by

Where f'(a) is the first derivative of f at x=a

The questions gives us this function

And the point a=4. Let's compute f(a)

We are using only the positive root. Now we compute the derivative

Replacing the values into the equation

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )
