Add the following points to your table.

x  g(x)
-1 -4
-1 -8

By doing this, the input of -1 has two different outputs. They are -4 and -4. Since an input has more than one output, it is not a function.

Answer:

\left\begin{array}{cc}x&f(x)\\-1&7\\1&-8\\6&-9\end{array}\right


\left\begin{array}{cc}x&g(x)\\-1&7\\6&-8\\6&-9\end{array}\right


Step-by-step explanation:

The given table for f(x) is


\left\begin{array}{cc}x&f(x)\\-1&--\\--&-8\\6&--\end{array}\right

For f(x) to be a function, we must complete the table in such a way  that its graph will pass the vertical line test. In order words none of the inputs should repeat.

So we can fill in the blank spaces under x, with any number apart from -1 and 6.


As for the output column, any number at all can go there and f(x) is still a function.


One of the possible solution is;

\left\begin{array}{cc}x&f(x)\\-1&7\\1&-8\\6&-9\end{array}\right



The given table for g(x) is


\left\begin{array}{cc}x&g(x)\\-1&--\\--&-8\\6&--\end{array}\right

For g(x) not to be a function, we must complete the table in such a way  that its graph will fail the vertical line test. In order words one of the inputs should repeat.

So we can fill in the blank spaces under x, with either -1 or 6.


As for the output column, any number at all can go there and g(x) will still not be a function.


One of the solution is;

\left\begin{array}{cc}x&g(x)\\-1&7\\6&-8\\6&-9\end{array}\right

What is the area of the base of a paper cone, in square inches, with a height of 15 inches and a volume of 900 cubic inches?
Mamont248 [21]

Answer:

180 sq. in.

Step-by-step explanation:

The formula for the volume of a circular cone is V = (πr^2h)/3

So, 900 = (15πr^2)/3

2700 = 15πr^2

180 = πr^2 = area of the circular base
