What is the limit of (x+2)(3x+1) as x approaches 2? What if the limit was of (3x+1) as x approaches 2?

Here are the solutions to the questions from the image.

SECTION A

1. $\lim_{x \to 2} (x+2)(3x+1)$ Substituting $x=2$: $(2+2)(3(2)+1) = (4)(6+1) = (4)(7) = 28$. Self-correction: The given options (a) 5, (b) 6, (c) 7, (d) 8 do not include 28. It is highly probable that the question intended to ask for $\lim_{x \to 2} (3x+1)$. Assuming the question is $\lim_{x \to 2}
