## Question:

Consider the function f(x) = 3 +{eq}\int^{1+x^2}_2 5/2(1 + t^2) {/eq} dt.

(a) Find the linearization of f(x) at a = 1.

(b) Use the linearization in (a) to approximate {eq}\int^{1+(1.1)^2}_2 5/2(1 + t^2) {/eq}dt.

## Linearization:

When functions are extremely difficult to evaluate, the process of linearization helps us approximate the value of the function. The formula to perform linearization is given as {eq}f(x) = f(x_0) + h \cdot f'(x_{0}) {/eq}, where {eq}f(x)_0 {/eq}, {eq}h = x - x_0 {/eq}, and {eq}f'(x_{0}) {/eq}, are provided in order to find the {eq}f(x) {/eq} value.
