If x=3+bi, then
You know that then
Two possible complex numbers satisfy these conditions:
As you can see the possible value of b is 2.
Answer: correct choice is A.
The piecewise function h(x) is shown on the graph. What is the value of h(2)? −2 −1 0 3
2 answers:
We need to find the value of h(2).
h(2) represents the value of h function for x=2.
We need to check the value of function on the graph where h is 2.
From the graph, we can see for x=2, we have a solid dot for y coordinate at 0 and a hollow dot at y coordinate at 3.
Because hollow dot represents excluded value.
Therefore, we would take y coordinate of solid dot of the graph at x=2.
Therefore, f(2) = 0.
<h3>Correct option is third option, that is 0.</h3>
