The total distance traveled by Alfred is the sum of the distance he traveled before and after refueling.
The distance he traveled before refueling is 150 miles. After refueling, the distance he traveled is the product of his speed and time, x hours. Therefore, his total distance traveled is,
y = 60x + 150
The absolute value expression has a V shape. The range of a positive absolute value expression starts at its vertex and extends to infinity. The absolute value is in the denominator, which means it can not be zero.
(0, ∞)
{y|y>0}
Hope this helps
