Let's analyze and solve the questions one by one.

### Question 1
The problem gives us a function:
\[
f(x) = 3x^2 - 2
\]
and asks for the limit representing the derivative at \( x = 2 \):
\[
\lim_{{h \to 0}} \frac{{f(x + h) - f(x)}}{h} \quad \text{at } x = 2.
\]

To solve this:
1. Calculate \( f'(x) \), the derivative of \( f(x) \).
   \[
   f(x) = 3x^2 - 2
   \]
   The derivative, \( f'(x) \), is:
   \[
   f'(x) = \frac{{d}}{{dx}}(3x^2 - 2) = 6x.
   \]

2. Substitute \( x = 2 \) to find the slope at this point:
   \[
   f'(2) = 6 \cdot 2 = 12.
   \]

Thus, the outcome of the limit (and the slope of the tangent line at \( x = 2 \)) is **12**, so the answer is **(b) 12**.

### Question 2
The problem asks for the slope of the function at \( x = 5 \) for:
\[
f(x) = 6\sqrt{2x - 2}.
\]

To find this slope:
1. Rewrite \( f(x) \) to make it easier to differentiate:
   \[
   f(x) = 6(2x - 2)^{1/2}.
   \]

2. Use the chain rule to differentiate:
   \[
   f'(x) = 6 \cdot \frac{1}{2} (2x - 2)^{-1/2} \cdot 2 = \frac{6}{\sqrt{2x - 2}}.
   \]

3. Substitute \( x = 5 \):
   \[
   f'(5) = \frac{6}{\sqrt{2 \cdot 5 - 2}} = \frac{6}{\sqrt{10 - 2}} = \frac{6}{\sqrt{8}} = \frac{6}{2\sqrt{2}} = \frac{3}{\sqrt{2}}.
   \]

Since none of the options match \( \frac{3}{\sqrt{2}} \), the answer is **(e) none of these**.
