The problem shown in the image is:

$\lim_{x \to -3} x^3 + 1 = 26$

To solve this, we simply substitute $x = -3$ into the expression $x^3 + 1$.

1. $x^3 = (-3)^3 = -27$
2. $x^3 + 1 = -27 + 1 = -26$

However, this results in $-26$, not 26 as indicated in the equation. So the equation $\lim_{x \to -3} x^3 + 1 = 26$ is not true, since substituting $x = -3$ gives $-26$, not 26.

Here are 5 questions you might explore next:

1. What is the formal definition of a limit?
2. How can limits be used to analyze the behavior of functions as they approach a point?
3. What happens if we have a discontinuity at $x = -3$?
4. How could we modify the function so that the limit equals 26?
5. What are some other examples of cubic functions with limits at specific points?

Tip: Always verify if substituting the limit point directly into a polynomial function yields the correct result, as limits of polynomials are straightforward.
