How many quadrants must the image of the positive scale function y = (K & # 178; + 1) x (k is a constant, K ≠ 0) pass through

How many quadrants must the image of the positive scale function y = (K & # 178; + 1) x (k is a constant, K ≠ 0) pass through

It is easy to know that K ^ 2 + 1 > 0
So we have to go through one or three quadrants
