Given that, Thomas is ordering a soft pretzel at Papa's Pretzel. Papa Pretzel charges $3 for the pretzel and $0.50 for each topping, with a maximum of 4 toppings on a pretzel.
Let, x denotes the number of toppings.
So, Cost, y = 3 + 0.5x, 0 ≤ x ≤ 4 as the maximum number of toppings is
So, the domain = [0, 4]
When x = 0,
y = 3 + 0 = 3
When x = 4,
y=3 + (0.5 * 4)
=3 + 2
=5
So, the range is [3, 5]
