Express the graph shown in color using interval notation Als

Express the graph shown in color using interval notation Also express the graph as an inequality involving Choose the connect interval notation below that is represented by the graph A. (- infinity, 1) B. (1, infinity) C. (- infinity, 1) D. (1, infinity)

Solution

The given colored line is from 1 to infinity.

since 1 is included in line so closed notation on left side

and we for infinity open notation so, interval will be [1, infinity)          (B) ans
