Look at the function shown in the figure.
When is the function positive?
The function we see is a decreasing function,
Because as X increases, the value of Y decreases, creating the slope of the function.
We know that this function intersects the X-axis at the point x=-4
Therefore, we can understand that up to -4, the values of Y are greater than 0, and after -4, the values of Y are less than zero.
Therefore, the function will be positive only when
X < -4
