What is the graph of the function f(x) = 1/3x^2
1 answer:
Answer: See the figure attached.
Step-by-step explanation:
1. The function shown is of a parabolic equation whose coefficient is positive. This means that the graph will have the shape of a concave parabola.
2. To verify it we can introduce values to the function. Then, you have:
x y
0 0
1 1/3
-1 1/3
2 4/3
-2 4/3
We can see that the function shown in the graph does not match that of the equation
The graph of this function is shown in the figure attached.

Answer:
240 m
Step-by-step explanation:
Figure is attached.
The distance the particle travels is the area under the v-t graph over the time interval from 0 min to 4 min. The reason you can't just multiply velocity by time is that the velocity is changing at a constant rate over the given time interval (the line is going upward--the particls is speeding up).
What's the area under the graph?
The red outline forms a trapezoid. The area of a trapezoid is where the <em>b</em>'s are the lengths of the two parallel base and <em>h</em> is the height (the distance between the bases).
Reading the graph carefully (notice the scales!)...
