Find the linear approximation of the function f(x) = 4 − x at a = 0. L(x) = $$ Incorrect: Your answer is incorrect. Use L(x) to approximate the numbers 3.9 and 3.99 . (Rou

Step-by-step explanation:

The linear approximating polynomial is:

Given: at a=0

f(0)=4-0=4

f'(x)=-1, Therefore: f'(a)=-1

Therefore, the linear approximation of f(x) at a=0 is:

We then use our result to approximate 3.9 and 3.99.
