Which of the following are ordered pairs for the given function? select all that apply. f(x) = 1 + x (1, 0) (0, 2) (3, 3) (1, 2) (0, 1)

F(x) is the same thing as y, and all ordered pairs have an x and y.  we will fill in the equation with the given x value and see if we "get back" the y value.  f(1)=1+1 which is 2.  the y coordinate in the first pair is 0, not 2.  first point doesn't work.  second point has an x value of 0, 1+0 = 1, but our y value is 2.  second point doesn't work either.  third point, same thing. 3+1 = 4 not 3.  fourth point has an x value of 1: 1+1=2 and our y value is 2, so the fourth point works.  the last point has an x value of 0: 1+0=1 and our y value is 1, so the 4th and 5th points work in that function.
