1. **State the problem:**
Find the values for the given functions:
a) Calculate $g(1) + h(-3)$ and then divide by 4.
b) Calculate $\sqrt{h(-1)}$.
2. **Calculate $g(1)$:**
Given $g(x) = -\frac{3}{x} + 2$, substitute $x=1$:
$$g(1) = -\frac{3}{1} + 2 = -3 + 2 = -1$$
3. **Calculate $h(-3)$:**
Given $h(x) = 5x^2 - 4x$, substitute $x=-3$:
$$h(-3) = 5(-3)^2 - 4(-3) = 5(9) + 12 = 45 + 12 = 57$$
4. **Calculate $g(1) + h(-3)$:**
$$-1 + 57 = 56$$
5. **Divide by 4:**
$$\frac{56}{4} = 14$$
6. **Calculate $h(-1)$:**
$$h(-1) = 5(-1)^2 - 4(-1) = 5(1) + 4 = 5 + 4 = 9$$
7. **Calculate $\sqrt{h(-1)}$:**
$$\sqrt{9} = 3$$

8. **Describe the transformations for $y = f| -4(x - 6)| + 2$:**
- The expression inside the absolute value is $-4(x - 6)$.
- The factor $-4$ causes a vertical stretch by a factor of 4 and reflection over the y-axis inside the absolute value.
- The $(x - 6)$ shifts the graph 6 units to the right.
- The $+2$ outside shifts the graph 2 units upward.
So, the graph is a V-shaped absolute value function shifted right 6 units, vertically stretched by 4, reflected inside the absolute value, and shifted up 2 units.

9. **True or False question:**
"A function can have more than 1 y-intercept."
This is false because a function must pass the vertical line test, which means it can only cross the y-axis once. Multiple y-intercepts would violate this rule.
**Final answers:**
a) $\frac{g(1) + h(-3)}{4} = 14$
b) $\sqrt{h(-1)} = 3$
c) Transformations: shift right 6, vertical stretch by 4, reflection inside absolute value, shift up 2.
d) False, a function cannot have more than one y-intercept.
