if you want to write an equation, it is:
10 + x divided by 6
this is what i believe is the answer. (may not be right but try )
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
the normal distribution is symmetric about its mean.
so answer c) must be true.
