Find the linear approximation of the function g(x) = 3√(1 + x) at a = 0.
Solution:
Linearization is a mathematical process of determining the linear approximation of inputs and corresponding outputs.
Given, the function g(x) = 3√(1 + x) = 3 (1 + x)1/2
We have to find the linearization L(x) of the function at a = 0.
Using the formula,
L(x) = g(a) + g’(a)(x - a)
Now,
g(x) = 3(1 + x)1/2,
g(a) = f(0) = 3
g’(x) = 1/2 (1 + x) - 1/2
g’(a) = g’(0) = 1/2.(1 + 0) - 1/2 = 1/2
Substituting the values of g(a) and g’(a), the function becomes
L(x) = 3 + (1/2)(x - 0)
Therefore, the linearization of g(x) = 3√(1 + x) at a = 0 is L(x) = 3 + x/2.
Find the linear approximation of the function g(x) = 3√(1 + x) at a = 0.
Summary:
The linearization of the function g(x) = 3√(1 + x) at a = 0 is L(x) = 3 + x/2.
