$\textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ V=2034.72\\ h=18 \end{cases}\implies 2034.72=\pi r^2(18) \implies \cfrac{2034.72}{18\pi }=r^2 \\\\\\ \cfrac{2034.72}{18(3.14) }=r^2\implies \sqrt{\cfrac{2034.72}{18(3.14) }}=r\implies 6=r$

Which statement best describes the function represented by the graph?

forsale [732]

Answer:

Step-by-step explanation:

You read a graph from left to right, just like you would read words on a page in a book. At the left-most "side" of this graph, we are way up at positive infinity. As we move from left to right, the graph begins to drop in y values. A drop in y values indicates a decreasing graph. So it's decreasing, we have that part. As the graph grows up into y values that increase forever, it will also grow in the x direction to negative infinity. As the graph decreases in y values from left to right, the x values increase into positive infinity. So your choice is the second one: The function is decreasing on the interval (-∞, ∞).

Write the range of the function using interval notation.

nalin [4]

Given:

The graph of a function.

To find:

The range of the given function using interval notation.

Solution:

Range: The set of y-values or output values are known as range.

From the given graph, it is clear that the function is defined for $0$ and the values of the functions lie between -2 and 2, where -2 is excluded and 2 is included.
