Answer 2

To analyze the function $F(x) = 8x^3 + 12x^2 - 6x - 2$, we can examine its key properties such as its degree, leading coefficient, roots (zeroes), and general behavior.

1. Degree: The highest power of the variable $x$ in the function is $x^3$, so the degree of the function is 3.

2. Leading coefficient: The coefficient of the term with the highest power of $x$ (in this case, $x^3$) is 8. Therefore, the leading coefficient is 8.

3. Roots (Zeroes): The roots of the function are the values of $x$ for which $F(x) = 0$. To find the roots, we need to solve the equation $F(x) = 0$:

$8x^3 + 12x^2 - 6x - 2 = 0$

Finding the exact solutions for cubic equations can be challenging, but you can use numerical methods or graphing tools to estimate the roots. In this case, there might be one or more real roots and possibly some complex roots.

4. General Behavior: Since the degree of the function is odd (3), it means that as $x$ approaches negative infinity, the function $F(x)$ will also approach negative infinity, and as $x$ approaches positive infinity, $F(x)$ will approach positive infinity.

5. Turning Points: A cubic function can have up to two turning points, where the function changes its concavity. To find these turning points, you need to calculate the first and second derivatives of the function and find the values of $x$ where the first derivative is equal to zero.
