Step 1: Utilizing the general equation for a cosine function, {eq}y=Acos(B(x-D))+C {/eq}, substitute the given value of ... WebStep 1: We replace x by x − π 3 which shifts the graph π 3 units to the right. (See figure (a).) 🔗. Step 2: Then we replace x by 2 x to get g ( x) = sin ( 2 x − π 3) which compresses the graph horizontally by a factor of 2, including the horizontal shift. This reduces the horizontal shift from π 3 to . π 6.
