Question

Use the image to answer the question.

A coordinate plane's axes range from negative 10 to 10, both by 1-unit increments. 2 lines are plotted, 1 solid and 1 dotted. The dotted line is labeled 'Function upper B' and the solid line is labeled 'Function upper A.'

Describe the transformation from Function A
to Function B
. Select the option number that corresponds to the correct direction of the translation after the reflection. Then enter the number of units that the function was translated.

Option 1: down

Option 2: up

(1 point)
The function is reflected over the y-axis and then shifted
by
units.

Answer 1

I can't see the plotted lines clearly from your description. Could you either re-upload the image or give the coordinates of one point on Function A and the corresponding point on Function B (or give their y-intercepts)?

How to get the answer yourself:
- Reflecting over the y-axis changes x to −x but does not change y-values at x = 0, so the y-intercept of A is the same after the reflection.
- So the vertical translation after the reflection is just the difference in y-intercepts: shift = y-intercept(Function B) − y-intercept(Function A).
- If that difference is positive, the translation is up (Option 2). If negative, it's down (Option 1). The number of units is the absolute value of that difference.

Send the y-intercepts or a clear image and I’ll give the exact option and number of units.
