Answer:
y = 26x
Explanation:
Let x = number of medium potatoes.
Let y = amount of carbohydrates in grams.
1 potato has 26 * 1 grams of carbohydrate.
2 potatoes have 26 * 2 grams of carbohydrate.
3 potatoes have 26 * 3 grams of carbohydrate.
x potatoes have 26 * x grams of carbohydrate.
26 * x is the same as 26x.
The function is
y = 26x
