Which transformations could have taken place to map AABC to AA"B"C"?
O a reflection and a dilation
O a rotation and a dilation
O a translation and a dilation
O a reflection and a translation

a dilation and translation

Step-by-step explanation:

we know its a dilation because the lines of congruency are in the same area but the triangles are of different sizes

we know it's a translation because the triangles are in two different places instead of having something overlap

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
