Question

HELLPP! At a construction site, workers are moving dirt from a pile to fill a hole. The function graphed models the volume of dirt, y, in cubic feet, remaining in the pile after x hours.
Identify the y-intercept.
Explain what the y-intercept represents.
Identify the x-intercept.
Explain what the x-intercept respresents.
Explain what the x-intercept represent

Answer 1

We are given graph for the Volume of dirt remaining at a construction site.

x axis represents time in hours.

y-axis represents volume in ft^3.

y-intercept is a point on y-axis, where line cut y-axis.

According to graph, line cuts y-axis at 450.

Therefore, y-intercept is 450.

y-intercept represents the initial volume of the dirt.

Therefore, initial volume of the dirt is 450 ft^3.

x-intercept is a point on x-axis, where line cut x-axis.

According to graph, line cuts x-axis at 6.

Therefore, x-intercept is 6.

x-intercept represents the time when dirt has finished.

Therefore, after 6 hours the dirt gets finish.
