Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

Expert Solution

Step 1

Given Y= 15X-25

X is the number of grams of carbohydrates.

Y is number of calories.

From above equation we observe that Y is directly proportional to X and some constant.
