I think you have to combine like terms to solve this one. (6d - 3d) + (5 - 2) = 3d + 3
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.
