Can someone show me how to do this function problem?
Suppose f(xy)=xy−6. Compute the following values:
f(x+2yx−2y)=?
f(xy4x2y3) =?
I'm not sure where to start?
Update:
Sorry its:
f(x+2y, x−2y) =
f(xy, 4x^2y^3) =
Update 2:
and the original problem is f(x,y)
Update 3:
and the original problem is f(x,y)=xy-6

work backwards to figure out what the original f(x) would be by replacing all (xy) with (x)
so, f(x) = x - 6
after that, plug away!
