The discussion focuses on the challenges of understanding inequalities in mathematical functions. Participants express a desire for a step-by-step approach to grasp these concepts better. The conversation highlights the significance of the function f(x) in determining the values above, on, or below the x-axis. Clarifications are sought regarding the specific inequalities related to a particular item, emphasizing the relationship between f(x) and y values. Overall, the thread aims to provide guidance on overcoming struggles with mathematical inequalities.

$f(x) > 0$ is any part of the graph that is above the x-axis
$f(x) = 0$ is any part of the graph that crosses or touches the x-axis
$f(x) < 0$ is any part of the graph below the x-axis
$f(x) = 0$ is any part of the graph that crosses or touches the x-axis
$f(x) < 0$ is any part of the graph below the x-axis

Do you not understand that in "y= f(x)" any value of f is a "y" value? f(x)= 0 means y= 0 so that is a point on the x- axis. That is what goes into the first two blanks. For the other two we need to know how "f(x)" is defined here.
