The difference between x and 5, divided by 6
SashulF [63]

Answer:

The correct way to interpret the difference of a number divided by 6 and 5 equals 8 is

n/6 - 5 = 8. I believe that another tutor has misled you; there should be only one division, applying to n only.

If f(g(x)) = (x-3)^4<br> what is f(x) and g(x)
Lelechka [254]

One possible solution is

f(x) = x^4

g(x) = x-3

Since

f(x) = x^4

f(g(x)) = ( g(x) )^4

f(g(x)) = ( x-3 )^4

=================================================

Another possible solution could be

f(x) = x^2

g(x) = (x-3)^2

Because

f(x) = x^2

f(g(x)) = ( g(x) )^2

f(g(x)) = ( (x-3)^2 )^2

f(g(x)) = (x-3)^(2*2)

f(g(x)) = (x-3)^4
