MarkFL said:Let's look at the first place where an answer is expected, that is to find $g(-2)$.
We are given the rule:
\(\displaystyle g(x)=f(-x)+1\)
Therefore, we may state:
\(\displaystyle g(-2)=f(-(-2))+1=f(2)+1=-1+1=0\)
Can you try the others in the same way?
OMGMathPLS said:Ok so we're including the - we are plugging it in with the negative.
That makes more sense.
MarkFL said:Let's look at the next one...what did you do to get 0?
OMGMathPLS said:I'm not sure why we are putting it into the (x) first and then = f(x) if we're trying to find g(x).
MarkFL said:In order to find $g(x)$, we need to use the given rule:
\(\displaystyle g(x)=f(-x)+1\)
So, we do the following:
1.) Negate the input to $g$.
2.) Pass this negated input to $f$.
3.) Add 1 to the value obtained from $f$.
4.) This is the value of $g$.
So, for the second one, we find:
1.) \(\displaystyle -(-1)=1\)
2.) \(\displaystyle f(1)=2\)
3.) \(\displaystyle 2+1=3\)
4.) \(\displaystyle g(-1)=3\)
Or, as I did the first one:
\(\displaystyle g(-1)=f(-(-1))+1=f(1)+1=2+1=3\) :D
Table functions are built-in functions in programming languages that are used to manipulate data stored in tables or arrays. They are important because they allow for more efficient and organized ways of working with large amounts of data.
Table functions work by taking in input data in the form of a table or array, performing a specific operation on the data, and then returning the result in the same format. This allows for easy integration into existing data structures.
Some common types of table functions include filtering functions, which allow for the selection of specific data based on certain criteria, and aggregation functions, which combine multiple data points into a single value. Other types include sorting functions, pivot functions, and join functions.
To use table functions in your code, you will need to understand the specific syntax and parameters for the function you want to use. Most programming languages have documentation or tutorials available for their built-in table functions, which can help you understand how to use them in your code.
While table functions can be very useful, they can also be more complex and require a deeper understanding of programming concepts. Additionally, some table functions may have limitations in terms of the types of data they can handle or the size of data they can process. It is important to thoroughly test and understand a table function before implementing it in your code.
