Given:
The graph.
To find:
The domain and range of the graph.
Solution:
The three points on the graph are (-3,3), (0,0) and (3,3).
We know that, domain is the set of input values or x-values. So,
Domain = {-3,0,3}
We know that, Range is the set of output values or y-values. So, elements for range are 3,0,3. But a set contains only distinct elements. So, consider 3 once in range.
Range = {0,3}
Therefore, the correct option is b.
5pi/4 is located in quadrant III.
In Q III, sin and cos are negative, tan is positive.
T-bar for 5pi/4 is pi/4.
sin and cos are - (sqrt 2)/2
Tan is 1
