The graph of this function is a straight line passing through the x axis at (10,0) and the y-axis at (0,10). The line continues to the left and right without bounds.
So the Domain is all Real Numbers and the Range is all Real Numbers.
His estimate is reasonable. But only if Michael is less than 2 years old.
