Which is the graph of the step function f(x)?

To determine the graph of the function f(x), consider such steps:

1 step. Since for all then you should take all points from the line for which - that is the left part of the line and point with x-coordinate -1 must be unfilled, because the sign is <.

2 step. Since for all then you should take all points from the line for which - that is the segment part of the line and points with x-coordinate -1 and 1  must be filled, because the signs are with notion "or equal to".

3 step. Since for all then you should take all points from the line for which - that is the right part of the line and point with x-coordinate 1 must be unfilled, because the sign is >.

correct choice is B

angle q= 92 degree

step-by-step explanation:

the solution is in the picture

when a quadrilateral is inscribed in a circle, the opposite angles are supplement to each other. in other words, the sum of the 2 angle is 180 degree
