The region covered by y ≥ x-1 is the line y = x-1, and the region above it, Option B. ( graph D)
Inequality is defined as the relation which makes a non-equal comparison between two given functions.
Suppose there is inequality given as;
y ≥ f(x)
The region it covers is the region of value pairs (x,y) for which this inequality holds true.
For a function y = f(x), there is y > f(x) on one side of the graph of the function y = f(x) in XY plane, and on other side there is y < f(x).
For this case, the region covered by inequality y ≥ x-1
The line y = x -1
Take x = a, move vertically up above the line y = x-1.
The region above y = x-1 is the region where x is the same, but y increased than the value of y from y =x-1
That means in the region above y =x-1,
we have y > x-1
Hence, the region covered by y ≥ x-1 is the line y = x-1, and the region above it, Option B. ( graph D)
