Solve for x∈R3x-2<13b) 23-x-1≥7When the equal sign in equation is replaced by >, <, ≤, or ≥, then the equation becomes an inequality.Linear inequalities can be solved algebraically but quadratic, cubic, etc. can be solved more easily using a graph or algebraically with a table/sign diagram.Example 1Solve x2-7x+12<0Example 2Solve x3-5x2+6x≥0Example 3 Solve x3+4x2+x-6<0*You may run out of space on these next two examples.Example 4Solve -2x3-6x2+12x+16≤0 ................
