Describe the effect of the transformation.

A. Vertical translation of -7 units.
B. Vertical stretch without reflection
C. Horizontal translation of -7 units
D. Vertical stretch without reflection

Is the answer A

  • Algebra 1 -

    D.Vertical stretch with reflection
    It was supposed to say this

  • Algebra 1 -

    y---->7y would "stretch" it by a factor of 7
    y ---- -7y would not only stretch it but also reflect it in the x-axis.

    so it looks like D after your correction of the wording
