10 points and brainliest to correct answer yay

which graph shows the image of aabc reflected over the y-axis ?

The answer is choice c

If you reflect over the y-axis, you're basically just folding the shape over the y-axis (vertical up/down line) which means if you were to look at the points, A-A' would share teh same y coordinate point but the x coordinate point would be inversed (become negative)

going through your choices
A. looks like its reflected over the x-axis
C looks like its reflected over the x-axis, then y-axis
D. looks like a translation from the 3rd quadrant to the 1st

B. is a reflection over the y-axis

Technically speaking, histograms are another version of bar charts, if you need to work one out then skim through google hope-o that -o!
