1. The problem is to analyze and understand the given functions:
2. The functions are:
1. $y = x + 4$
2. $y = |x|$
3. $x = |y|^2$
4. $y = -2(x+4)^2 - 1$
3. Let's discuss each function:
4. For $y = x + 4$:
- This is a linear function with slope 1 and y-intercept 4.
- The graph is a straight line.
5. For $y = |x|$:
- This is the absolute value function.
- It outputs the non-negative value of $x$.
- The graph is a V shape with vertex at the origin.
6. For $x = |y|^2$:
- This can be rewritten as $x = (|y|)^2 = y^2$ since squaring removes the absolute value.
- This is a parabola opening to the right.
7. For $y = -2(x+4)^2 - 1$:
- This is a quadratic function with vertex at $(-4, -1)$.
- The parabola opens downward because of the negative coefficient.
8. Summary:
- 1st function: linear line.
- 2nd function: V-shaped absolute value.
- 3rd function: parabola opening right.
- 4th function: downward parabola shifted left and down.
Final answers are the descriptions and forms of these functions.
