P.3 of 10 For question 6 and 7, consider the following function: f(x) = cos(2-2x) , 6. If the graph of y=f(x) is obtained by a few transformations from y=cosx which of the following is correct? a. y=f(x) is obtained from y=cos x by a reflection in the y-axis, a horizontal 1 compression by a factor of and a translation of 1 unit to the right. 2 b. y=f(x) is obtained from y=cos x by a reflection in the y-axis, a horizontal stretch by a factor of 2 and a translation of 2 unit to the right. C. y=f(x) is obtained from y=cos X a horizontal compression by a factor of translation of 1 unit to the left. and a 2 d. y=f(x) is obtained from y=cos x by a reflection in the y-axis, a horizontal stretch by a factor of 2 and a translation of 2 unit to the left. 7.
