It seems like you are referring to calculating the sum of graphical limits of certain functions. Graphical limits generally involve finding the behavior of functions as they approach a certain value (often infinity or a particular point) based on their graphs, which is a crucial concept in calculus.

However, since you mentioned the idea of “parent and well-known functions,” it’s important to clarify which functions you’re referring to. Typically, parent functions include:

• Linear: $f(x) = x$
• Quadratic: $f(x) = x^2$
• Cubic: $f(x) = x^3$
• Exponential: $f(x) = e^x$
• Logarithmic: $f(x) = \ln(x)$
• Trigonometric: $f(x) = \sin(x), \cos(x), \tan(x)$

The limits of such functions at certain key points (like approaching infinity, zero, or special values) might be required.

Example limits for parent functions:

1. Linear function: $\lim_{x \to \infty} x = \infty$
2. Quadratic function: $\lim_{x \to \infty} x^2 = \infty$
3. Exponential function: $\lim_{x \to \infty} e^x = \infty$
4. Logarithmic function: $\lim_{x \to \infty} \ln(x) = \infty$, but $\lim_{x \to 0^+} \ln(x) = -\infty$
5. Trigonometric functions: These have oscillatory behavior:
   • $\lim_{x \to \infty} \sin(x)$ does not exist because it oscillates between -1 and 1.
   • $\lim_{x \to \infty} \cos(x)$ similarly oscillates.

Summing graphical limits:

To sum the limits, it depends on the specific points of evaluation and functions in question. For example:

• Sum of limits at infinity: $\lim_{x \to \infty} (x + e^x + \ln(x)) = \infty + \infty + \infty = \infty$

However, a better understanding of the exact functions you want to work with and the points of interest (e.g., at $x \to \infty$ or $x \to 0$) would be helpful for a precise calculation.

Feel free to clarify or upload any graphs or specific functions you’d like analyzed!

Would you like more details on how to work with specific limits or any particular function's behavior?

Relative questions:

1. What are the limits of the basic parent functions as $x \to 0$ and $x \to \infty$?
2. How do oscillatory functions like sine and cosine behave as $x \to \infty$?
3. What is the difference between limits at infinity and limits at finite points?
4. Can graphical limits always be determined algebraically, or are there special cases?
5. How do vertical and horizontal asymptotes relate to graphical limits?

Tip: When calculating limits graphically, asymptotes provide key insights about the function's behavior near certain points.
