What 2 mistakes did Sandy make?

Question

Sandy was asked to describe the transformation of y = -3(x - 4)2 - 6 from the parent graph of y = x2.

She said it was shifted 4 units to the left, stretched by a factor of 3, reflected over the y-axis, and shifted 6 units down.

Answer 1

Remember that horizontal shifts go opposite of the sign, so the graph shifts 4 to the right.

The negative reflects over the x-axis.
