Question

a construction crew lengthened a road. it took 30 days. the graph shows the total length of the road (in kilometers) versus time (in days). find the range and the domain of the function shown. write your answers as inequalities, using x or y as appropriate. or, you may instead click on \empty set\ or \all reals\ as the answer. range: domain:

Explanation:

Step1: Identify domain (x-values)

The x-axis is time (days), with data from 0 to 30 days.
$0 \leq x \leq 30$

Step2: Identify range (y-values)

The y-axis is road length (km), with data from 90 to 270 km.
$90 \leq y \leq 270$

Answer:

range: $\boldsymbol{90 \leq y \leq 270}$
domain: $\boldsymbol{0 \leq x \leq 30}$
