Find the Maclaurin series for f(x) using the definition of a Maclaurin series. [Assume that f has a power series expansion. Do not show that Rn(x) → 0.] f(x) = ln(1 + 4x) f(x) = [infinity] n = 1 Correct: Your answer is correct. Find the associated radius of convergence R. R = Incorrect: Your answer is incorrect.

is should be y = 5x

step-by-step explanation:

correct me if im wrong

need more information

step-by-step explanation:

answer:   y=2x-3

step-by-step explanation:

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
