Solve the co,pound inequality
3x + 5 ≤ -1 or -2x -7 ≥ 5

Solve each

3x+5≤-1
minus 5 both sides
3x≤-6
divide 3
x≤-2

other

-2x-7≥5
add 7 to both sides
-2x≥12
divide both sides by -2 and flip sign
x≤-6

we got

x≤-2 or x≤-6
so since x≤-6 is actually inside the solution set of x≤-2, just shade from x≤-2
put dot at x=-2 and shade to left

The table shows a function. Is the function linear or nonlinear?
