9
It is a many to one function (APEX)
A cubic.
x3 - 11x2 + 18x = 0x (x2 - 11x + 18) = 0 . . . . x = 0 is a root.x (x - 9) ( x - 2) = 0 . . . . x = 9 and x = 2 are roots.X = 0, 2, 9
SUM
5x is a common factor of all terms:- 5x(x3+4x2+9)
what x3 equals 63 is:21x3=63
That's the same as x3 times x3 which equals x6
3xyz
31
y2=x3+3x2
One because if x3 = 1 then x must equal 1
