Is y = x square, y = x square + 1 a positive proportional function Why?

Is y = x square, y = x square + 1 a positive proportional function Why?

no
The positive scaling function is y = KX, K is not equal to 0
X is once
And here x is all quadratic, so it's not a positive scaling function

Is the square of y = x a positive proportional function
How to consider? Is k not 1? If K is greater than 0
I'm learning a function. This problem appears in my math exercise book
Isn't k 1 here? It's omitted. Why isn't k Changshu.
Please don't throw me a conclusion,

It's not a positive proportion function. It's very helpful to go to the website below
Generally, the relation between two variables X and y can be expressed as a function of y = KX (k is a constant and K ≠ 0), then y is called the positive proportional function of X
A positive proportion function belongs to a linear function, but a linear function is not necessarily a positive proportion function. A positive proportion function is a special form of a linear function, that is, in a linear function y = KX + B, if B = 0, that is, the so-called "intercept on the Y axis" is zero, then it is a positive proportion function. The expression of a positive proportion function is y = KX (k is the proportion coefficient)
When k > 0 (one or three quadrants), the larger K is, the closer the distance between the image and Y axis is. The value of function y increases with the increase of independent variable x
When k ＜ 0 (quadrant 2-4), the smaller the K is, the closer the image is to the y-axis. When the value of independent variable x increases, the value of Y gradually decreases

The second power of 2A times 8A of 3b, the second power of 9b, the second power of Y, the square of x times (- x, the square of Y) a, the square of - 1, the fourth power of 6a, the A-1
X parts of X squared y squared times (XY) parts of square - x squared

Please clarify the title
It's easy to be ambiguous
