Question

The linear graph shows the possible combinations of cakes and pies a club must sell to meet their fundraising goal. What is the domain of the graph? A) {x: 0 < x < 40} B) {x: 0 ≤ x ≤ 40} C) {x: 0 < x < 20} D) {x: 0 ≤ x ≤ 20}

Answer 1

`\{x: 0 \le x \le 40 \}`

Explanation:

Given

See attachment for graph

Required

The domain of the graph

To do this, we simply write out the range of value of the x-coordinate.

From the attached graph, the x values are:

`x = [0,40]` i.e. from 0 to 40 (both inclusive)

So, the domain is:

`\{x: 0 \le x \le 40 \}`
