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. |approximation - exact c. Compute the percent error in the approximation, 100 . where the exact value is given by a exact calculator. X f( x ) = X +2: a= 1; f(1.3) - . . a. L(x) = (Use integers or fractions for any numbers in the expression.) b. Using the linear approximation, f(1.3) ~ (Round to three decimal places as needed.) c. The percent error in the approximation is %. (Round to three decimal places as needed.)Integrate the expression. X 2x + 5dx
