For this question we will be approximating 172 without using a calculator. Instead we will use the tangent line to the curve f(x)=x2(a)(5 pts ) Since we are wanting to approximate 172 the natural function to ase is f(x)=x2, and as we are finding the approximation without the use of a calculator we noed to find a value "close" to 17 that we can evaluate easily, so let's choose x=16.Find the equation of the tangent line to f(x)=x2 at x=16, write your solution in slope-intercept form.(b)(4 pts) Now that we have the equation of the tangent line to f(x) at x=16 for values "close to"16 the tangent line is an approximation of f(x). So now we approximate using the tangent line y(use long-division to find the decimal form up to 2 decimal plecen):Find the approximation f(17)~~y|x||=17=
