Not all functions have inverse functions. Those that do are called invertible. For a function f: X → Y to have an inverse, it must have the property that for every y in Y, there is exactly one x in X such that f(x) = y.

Which of the following is a solution to the equation "y=3x-1"

nalin [4]

we have

$y=3x-1$

we know that

If the point is an equation solution, it must satisfy the equation.

case a) $(4,1)$

Substitute the values of x and y in the equation

$1=3*4-1$

$1=12-1$

$1\neq11$ -------> the point is not solution of the equation

case b) $(2,5)$

Substitute the values of x and y in the equation

$5=3*2-1$

$5=6-1$

$5=5$ -------> the point is solution of the equation

case c) $(4,3)$

Substitute the values of x and y in the equation

$3=3*4-1$

$3=12-1$

$3\neq11$ -------> the point is not solution of the equation

case d) $(0,-3)$

Substitute the values of x and y in the equation

$-3=3*0-1$

$-3\neq-1$ -------> the point is not solution of the equation

therefore

the answer is

The point $(2,5)$ is solution of the equation
