By translating the image of function y = lnx-2 into vector a = (negative 1,2), the image of function y = f (x) is obtained

By translating the image of function y = lnx-2 into vector a = (negative 1,2), the image of function y = f (x) is obtained

The function y = f (x) = ln (x + 1) is obtained by translating the image of y = lnx-2 according to the vector a = (- 1,2), so that f (x) = f (x) - 2x / (x + 2) = ln (x + 1)) - 2X / (x + 2) x > 0f (x) ′ = x ^ 2 / (x + 2) ^ 2 > 0 is constant, that is, f (x) increases monotonically with F (x) > F (0) = 0, that is, f (x) = f (x) - 2x / (x + 2) = ln (...)
