I have opened the image, which shows multiple mathematical problems related to function evaluation, using graphs, equations, and tables.

Let's break down each problem:

1. $f(3)$: We are asked to evaluate $f(3)$. The value of $f(x)$ can be found by using the graph provided. We look for the point on the graph where $x = 3$, and find the corresponding $y$-value.

2. Find $x$ when $f(x) = 4$: This requires finding when the $y$-value on the graph equals 4 and determining the corresponding $x$-value.

3. $g(-3)$: For the function $g(x)$, the values are given in the table. We look up $g(-3)$ in the table.

4. Find $x$ when $g(x) = 82$: We need to find the value of $x$ that makes $g(x) = 82$ in the table.

5. $h(16)$: The function $h(x)$ is given by a formula, so we substitute $x = 16$ into $h(x) = 3x - 23$ to find the value.

6. Find $x$ when $h(x) = 74$: This requires solving the equation $3x - 23 = 74$ for $x$.

7. $p(74)$: Using the table, find $p(74)$.

8. Find $t$ when $p(t) = 12$: This involves locating when the value of $p(t)$ equals 12 in the table.

I'll now calculate these values.Here are the results for the given problems:

1. $f(3) = 2$ (from the graph).
2. $x = 5$ when $f(x) = 4$ (from the graph).
3. $g(-3) = 9$ (from the table).
4. $x = 50$ when $g(x) = 82$ (from the table).
5. $h(16) = 25$ (calculated from $h(x) = 3x - 23$).
6. $x = \frac{97}{3} \approx 32.33$ when $h(x) = 74$ (solved from the equation $h(x) = 3x - 23$).
7. $p(74) = 58$ (from the table).
8. $t = 16$ when $p(t) = 12$ (from the table).

Would you like more details on any of these steps?

Here are some related questions to think about:

1. How would you interpret the behavior of $f(x)$ as $x$ increases?
2. What kind of function might describe $g(x)$ based on the table values?
3. How would you solve for $h(x) = 100$?
4. If the graph of $f(x)$ were extended, what would be the next logical value for $f(x)$?
5. What is the slope of the function $h(x)$?

Tip: When analyzing functions graphically, always double-check for turning points, as they can sometimes indicate maximum or minimum values.
