Answer:

Step-by-step explanation:

For this case we have the following function:
F (x) = 3x ^ 2 + 6x-24
We observe that it is a quadratic equation.
The graph is therefore a parabola.
Its cut points are:
(-4, 0)
(2, 0)
Answer:
See attached image to see graph of the function
The distance between Pittsburgh and Cleveland is 200 miles
<u>Solution:</u>
Given that,
Plane travels from Pittsburgh to Cleveland in 2 hours
Average speed of plane = 100 miles per hour
<em><u>To find:</u></em> Distance between these two cities
<em><u>The relation between speed distance and time is given as:</u></em>

On rearranging the above formula, we get

Distance between these two cities = 

Thus both the cities are 200 miles apart
