Find the x-coordinate of A", where A(1, 1) under the combination of a rotation 90 degrees counter-
clockwise about the origin and then translated 6
units to the right.

I think it's 5,1

Step-by-step explanation:

counter-wise of 1,1 is -1,1 and translating it 5 to the right makes it -1+6, 1 = 5,1

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
