At what values of x is the graph of the function y = -4x + 12 located below the Ox axis? How to determine?

We have the function y = -4 * x + 12;

It is necessary to determine at what values of x the graph of the function will be below the X-axis.

The X-axis, oddly enough, also has its own formula:

y = 0 is the X-axis formula.

You can plot a function graph and there determine at what x the graph is below the X axis, or you can solve the problem simply by drawing up an inequality.

-4 * x + 12 <0;

4 * x> 12;

x> 3.

We got that for all x greater than 3, the graph of the function will be located below the X-axis.
