To answer this question, we need to substitute the value of x into the given "rule" for the function as follows:
[tex]f(x)=x^2+6\Rightarrow f(-2)=(-2)^2+6\Rightarrow f(-2)=4+6[/tex]Therefore, we have:
[tex]f(-2)=10[/tex]Therefore, the ordered pairs (x, f(x)) are (-2, 10).
We can graph this point on the graph as follows:
Then, if we have other values for x, such as x = -1, x = 0, x = 1, and x = 2, we can follow the same steps as before for each value of x. Then, we need to evaluate the function for each value of x as follows:
x = -1
[tex]f(-1)=(-1)^2+6=1+6\Rightarrow f(-1)=7[/tex]x = 0
[tex]f(0)=(0)^2+6\Rightarrow f(0)=6[/tex]x = 1
[tex]f(1)=(1)^2+6=1+6\Rightarrow f(1)=7[/tex]x = 2
[tex]f(2)=(2)^2+6=4+6\Rightarrow f(2)=10[/tex]Now, to graph the function, we have the other ordered pairs as follows: (-1, 7), (0, 6), (1, 7), (2, 10).
Then, we can graph those points as follows:
As we can see, this is the graph of a parabola, with vertex (0, 6).
We can see more clearly if we use a graphing calculator as follows:
In summary, to graph the function, we need to evaluate the function for each value of x following the "rule" of the function, in this case we have:
