Question 1044571

*[tex \Large f(x)\ =\ x^2\ +\ 7]


Construct a two-column table:
<pre>
   x  | f(x)
--------------
      |
      |
      |
      |
</pre>

Pick any value you like for *[tex \Large x]; let's use 1 to start with.  Then evaluate *[tex \Large f(1)]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f(1)\ =\ (1)^2\ +\ 7\ =\ 8]


Now that you know that when *[tex \Large x\ =\ 1], *[tex \Large f(x)\ =\ 8].  So fill in the first row of the table.
<pre>
   x  | f(x)
--------------
   1  |  8
      |
      |
      |
</pre>
Do the same thing with 3 other different values for *[tex \Large x]


Once you have created 4 rows for your table, use the numbers in each row to create an ordered pair.  Your first ordered pair is *[tex \Large (1,\,8)], and the others depend on the numbers you select for the other three values of *[tex \Large x]


Once you have created all 4 of your ordered pairs, plot them on a graph and draw a smooth curve through them.  Hint: if you want an accurate picture of the curve for this function, choose 0 and some negative number for two of your *[tex \Large x] values.

My calculator said it, I believe it, that settles it
