Question

Determine the new coordinates of the point (π/6,√3/2) on the parent cosine function as it is transformed by the function g(x)=-4cos(1/3(x-π))

Answer 1

so plug in x=π/6 and calculate y.

or, apply the transformations
shift right by π
stretch x by 3
reflect across the x-axis
stretch y by 4

Answer 2

Thank you
