Answer the question by finding the linearization P1(x) of f at the given value of x.f(x) = e6x, at x = 0. Evaluate P1(0.06) and compare this value to f(0.06).
A. P1(0.06) = 1.11 f(0.06) = 1.433 B. P1(0.06) = 1.36 f(0.06) = 36.598 C. P1(0.06) = 1.36 f(0.06) = 1.433 D. P1(0.06) = 4.60 f(0.06) = 36.598
