For a linear function y = (M + 4) x + 2m-1, if y increases with the increase of X, and the intersection of its image and Y axis is below X axis, try to find the value range of M
∵ the first-order function y increases with the increase of X, ∵ k = m + 4 > 0, that is, m > - 4. The intersection of the image of the first-order function and the Y axis is below the X axis, ∵ B = 2m-1 < 0, that is, m < 12. The value range of M is - 4 < m < 12
