Question

Y=3x+6 обратима или нет ?

Answer 1

Ответ:

3x=Y-6

x=(Y-6)/3

обратима

Answer 2

A linear function of the form Y = mx + b, where m and b are constants, is invertible if and only if the coefficient "m" (slope) is not equal to zero. In the case of Y = 3x + 6, the coefficient of x is 3 (which is not equal to zero), so the function is invertible.

The inverse function would involve solving for x in terms of y:

Y = 3x + 6 3x = Y - 6 x = (Y - 6) / 3

So, the inverse of the function is x = (Y - 6) / 3, and it is indeed invertible.
