Find the equation of a cosine curve that is obtained by shifting the graph of y=cos(x) to the left 5 units and upward 9 units and vertically compressed by a factor of 4 and vertically flipped
Accepted Solution
A:
Wow! 1) shift graph to the left 5 units: y = cos (x+5) 2) shift graph upward 9 units: y = cos (x+5) + 9 3) vertically compressed by a factor of 4: y = (1/4) cos (x+5) + 9 4) vertically flipped: y = -(1/4) cos (x+5) + 9
