(3 points) The figure shows how a function f (x) and its linear approximation (.e., its tangent line) change value when I changes from co to co + dr. y = f(x) fredr) Suppose f(x) = x2 + 2x, xo = 2 and dr = 0.05. Your answers below need to be very precise, so use many decimal places. (a) Find the change Af = f (30+ dc) - f(:30). Af Error = 14f-df Af = f(x + dr) -...
(a) (b) Find the least squares approximation of f(x) = x2 + 3 over the interval [0, 1] by a function of the form y = ae? + bx, where a, b E R. You should write the coefficients a, b as decimal approximations, rounded to two decimal places. Let g(x) be the least squares approximation you found in the pre- vious problem. So g(x) = ae” + bx for some scalars a, b. Find the least squares approximation of...
