Question

In the graphical example, what are the domain and range of the given function?

Options

• Domain: \(\{x:0\le x\le7\}\); Range: \(\{y:2\le y\le8\}\)

• Domain: \(\{x:0\le x\le8\}\); Range: \(\{y:2\le y\le7\}\)

• Domain: \(\{x:2\le x\le8\}\); Range: \(\{y:0\le y\le7\}\)

• Domain: \(\{x:2\le x\le7\}\); Range: \(\{y:0\le y\le8\}\)

Answer 1

The given function contains input values from 0 through 8, so its domain is \(\{x:0\le x\le8\}\). Its output values run from 2 through 7, giving the range \(\{y:2\le y\le7\}\).
