Domain is the x axis and range is the y axis. The minimum is The domain is the x axis and the range is the y axis. C) (4,1) and maximum is (2,2) D) f(3) is 2 and E) is 1
Because we don't know the strarting point, so we can just assume that the X values are staring from negative infinity and ending at possitive infinity.
Then, we can see the highest Y value is at 2.5 and then decresing infinitly.
That's why we can write the domain and range this way.
