Answer:
27 is the answer
Explanation:
We have this proportion....
36 / 12 = x / 9 where x is the model door height
Cross-multiply
36*9 = 12 * x
324 = 12 *x divide both sides by 12
27 = x and that's the model height in centimeters
A is not a function
In table A, the x value of 4 goes to two different y values
To be a function each x value can only go to one y value
