Question

Solve the equation y = x -2, given the domain (2,3,4).
Question 4 options:
solution set is {(2,0),(3,0),(4,0)}
solution set is {(0,2),(1,3),(2,4)}
solution set is {(2,0),(3,1),(4,2)}
solution set is {2,3,4}

Answer 1

3

Answer 2

The domain is going to be all your x values, take turns pluggin in the numbers into the equation and see what comes out. For instance f(2) = (2) -2 = 0, so the first ordered pair will be (2,0)

Answer 3

substitute in each x value, x = 2, x =3, and x = 4 to find the corresponding y values, that that will be the solution, x = 2 gives y = 0, x = 3 gives y = 1 x = 4 gives y = 2

Answer 4
