Question

Give the domain and range.

a. domain: {3, 0, 3), range: {3, 0}
b. domain: {-3, 0, 3), range: {0, 3}
c. domain: {3, 0,3), range:{-3.0}
d. domain: (3, 0, 3), range: {0,3}​

Answer 1

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.
