Please solve for B
### Exercise: Symmetry and Graphing of Functions

**Instructions:**

1. **Determine if the following functions are even, odd, or neither. Show your algebraic justification for each.**

2. **Graph each function using a graphing calculator or using an online graphing tool (such as Desmos). Provide a screenshot of your graphs and identify the symmetry for each.**

#### Functions:

a) \( f(x) = -\frac{1}{2} |x| - 14x^8 + 7 \)

b) \( g(x) = \frac{-2x^3}{\sqrt{x^2+1}} \)

**Explanation of Terms:**

- **Even Function:** A function \( f(x) \) is even if \( f(-x) = f(x) \) for all \( x \) in the domain of \( f \).
  
- **Odd Function:** A function \( f(x) \) is odd if \( f(-x) = -f(x) \) for all \( x \) in the domain of \( f \).

**Graphs and Symmetry:**

Provide the graphs of the functions \( f(x) \) and \( g(x) \), using a graphing tool. Analyze the graphs to determine whether each function exhibits symmetry about the y-axis (even function), origin (odd function), or neither.
