The function f is defined for each positive three-digit integer n by f(n) = 2 x 3 y 5 z , where x, y and z are the hundreds, tens and units digits of n, respectively. if m and v are three-digit positive integers such that f(m) = 9f(v), then m – v = ?

step-by-step explanation:

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

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
