3. Consider the function f(x) = 4x + 5 on the interval [-1.1]. (a) Find the quadratic Taylor approximation fr(x) = co + Cl2 + 22x2. Calculate the Ci to four decimal places. (b) Find the quadratic Legendre approximation fl(x) = do + 01x + 22x. Calculate the ai to four decimal places. If the two approximations differ greatly, something is probably wrong. You may want to consult section 4 in the pdf I sent you on orthogonal polynomials.

please answer each part with steps included! 3. (10 points) Consider the function f(t) = 32 - 10, and notice that its positive zero is == V10. In this problem, you will use Calculus to estimate 10 to several decimal places. (A) (2 points) Since 3=V9 is close to V10, it is a good place to start. Write down the tangent line to y=f(x) at a = 3. (b) (2 points) Now find the intercept of the tangent line to...
