Understanding the Function and the Problem

The given function is $f(x) = x + 4$ . This is a simple linear function where the output is the input value plus 4. The problem asks us to find the ordered pair for the point on the graph where $x = 3p$ . This means we need to substitute $x$ with $3p$ in the function and find the corresponding value of $f(x)$ .

Substituting $x$ with $3p$ in the Function

To find the ordered pair, we need to substitute $x$ with $3p$ in the function $f(x) = x + 4$ . This gives us:

$f(3p) = 3p + 4$

Finding the Ordered Pair

The ordered pair for a point on the graph is in the form $(x, f(x))$ . In this case, we have $x = 3p$ and $f(x) = 3p + 4$ . Therefore, the ordered pair is:

$(3p, 3p + 4)$

Comparing with the Options

Let's compare the ordered pair we found with the options given:

A. ${$ (x, x+4)$}$ B. ${$ (x, 3p+4)$}$ C. ${$ (3p, 3p+4)$}$ D. ${$ (3p, x+4)$}$

The only option that matches our ordered pair is:

C. ${$ (3p, 3p+4)$}$

Conclusion

Therefore, the correct answer is option C. The ordered pair for the point on the graph where $x = 3p$ is $(3p, 3p + 4)$ .

Understanding the Graph of the Function

The graph of the function $f(x) = x + 4$ is a straight line with a slope of 1 and a y-intercept of 4. The point $(3p, 3p + 4)$ lies on this line. To visualize the graph, we can plot several points on the line and connect them with a straight line.

Plotting Points on the Graph

Let's plot several points on the graph of the function $f(x) = x + 4$ . We can choose several values of $x$ and find the corresponding values of $f(x)$ .

$x$	$f(x)$
0	4
1	5
2	6
3	7
4	8

We can plot these points on a coordinate plane and connect them with a straight line. The point $(3p, 3p + 4)$ lies on this line.

Visualizing the Graph

The graph of the function $f(x) = x + 4$ is a straight line with a slope of 1 and a y-intercept of 4. The point $(3p, 3p + 4)$ lies on this line. We can visualize the graph by plotting several points on the line and connecting them with a straight line.

Conclusion

In conclusion, the ordered pair for the point on the graph where $x = 3p$ is $(3p, 3p + 4)$ . This point lies on the graph of the function $f(x) = x + 4$ , which is a straight line with a slope of 1 and a y-intercept of 4.
