Question

Describe the transformation of f(x) = cos x to g(x) = cos(x + π/4). O A. f(x) is shifted units down. O B. f(x) is shifted / units to the right O C. f(x) is shifted 4 units to the left. O D. f(x) is shifted 7 units up. SUBMIT

Answer 1

Given,

The function is f(x)=cosx

The transformated function is g(x)=cos(x+π/4).

The graph of cosx is in the way the at the center of the coordinates or at x=0 the value of cosx is 1.

The graph of cos(x+π/4) transformed the curve and shifted it to left by π/4.

Hence, option C is correct.
