Question

How does the graph y=-2sin(x) - differ from its parent

Answer 1

The graph differs from the parent by the following transformations

• vertical stretch

• reflection

How to find the difference

The graph of y = -2 sin (x) from the parent function in the following ways

The parent function is y = sin x

The negative sign reflects the graph over the x-axis

The vertical stretch factor 2, increases the extents on the vertical direction
