Given the function y = (K + 5) x + (K-3), when k is, y is a linear function of X? When k is equal to, y is a positive proportional function of X When k is, y is a function of degree x? When k is equal to, y is a positive proportional function of X

Given the function y = (K + 5) x + (K-3), when k is, y is a linear function of X? When k is equal to, y is a positive proportional function of X When k is, y is a function of degree x? When k is equal to, y is a positive proportional function of X

Obviously, when K + 5 is not equal to 0, i.e. K is not equal to - 5, y is a linear function of X. when K-3 = 0, and K + 5 is not equal to 0, i.e. k = 3, y is a positive proportional function of X

If y is the inverse proportional function of Z, Z is the positive proportional function of X, and X is not equal to 0, then what is the functional relationship between Y and X?

Because y is the inverse proportional function of Z, then y = K / Z;
Because Z is a positive proportional function of X, then z = KX;
And X is not equal to 0
So we substitute z = KX into y = K / Z to get y = 1 / x, so y is the inverse proportion function of X (y = K / x, k = 1)
