If 2x + 3y = 4, y= (4 - 2x)/3. In function notation, f(x) = (4 - 2x)/3.
2 sin(x) - 3 = 0 2 sin(x) = 3 sin(x) = 1.5 No solution. The maximum value of the sine function is 1.0 .
y = x This is a line and a function. Function values are y values.
f(f(x)) = f(x). Only if f is 1-1 then we have a solution f(x)=x.
Y = x2
