Using a Tangent Line Approximation In Exercises 5-12, find the tangent line approximation T to the graph of f at the given point. Then complete the table. x 1.9 1.99 2 2.01 2.1 f(x) f(x) f ( x ) = x ,       ( 2 , 2 )

To determine

To calculate: The missing values in the table x1.91.9922.012.1f(x)T(x) after obtaining the tangent line approximation T for the provided function f(x)=x and the point (2,2).

Explanation

Given:

The function f(x)=x and the point (2,2).

The table,

x1.91.9922.012.1f(x)T(x)

Formula Used:

For the function f and a point (c,f(c)), the tangent line approximation is given by:

T(x)=f(c)+f'(c)(xc)

Calculation:

Differentiate the provided function,

f(x)=xf'(x)=12x

Now calculate the derivative at 2
