answer: reflected about y axis and vertically up by 4 .
f(x) = x
for -f(x) it becomes -f(x) = -x ) [ multiplying by -1 both sides ]
to find -f(x) +4 ,we add 4 both sides of equation (1) ,we get
-f(x) +4 = -x +4 (2)
therefore on applying two transformation [ first reflection about y axis and translated 4 units upwards makes the function -x+4
answer:x = 1.2 and y = -3.6 → (1.2, -3.6)
all you gotta do is add.
