Could I have some help with these two linear approximation and percent errror problems there are 2

a. Write the equation of the line that represents the linear approximation to the following function at the given point a. b. Use the linear approximation to estimate the given quantity. c. Compute the percent error in the approximation, 100 . [approximation - exact/ , where the exact value is given by a calculator. exact f(x) = 12 - x- at a = 2; f( 1.9) a. L(x) = b. Using the linear approximation, f(1.9) ~ (Type an integer or a decimal.) c. The percent error in the approximation is 1% (Round to three decimal places as needed.)K a.
