Answer:
A(2,2)
Step-by-step explanation:
Let the vertex A has coordinates
Vectors AB and AB' are perpendicular, then
Vectors AC and AC' are perpendicular, then
Now, solve the system of two equations:
Subtract these two equations:
Substitute it into the first equation:
Then
Rotation by 90° counterclockwise about A(2,2) gives image points B' and C' (see attached diagram)

Answer:
-25
Step-by-step explanation:
g(f(3))= g(-5)
=4(-5)-5
