Graph the function f(x)=X^3 +3 X^2 +2

Solution

To graph the function f(x)=x3+3x2+2f(x) = x^3 + 3x^2 + 2, let's go through the steps:

1. Identify the basic characteristics of the function:

  • Degree: The function is a cubic polynomial, meaning it has degree 3.
  • Leading Coefficient: The coefficient of x3x^3 is positive, so the graph will rise to the right and fall to the left.
  • Intercepts: Let's find the yy-intercept and the xx-intercepts.

2. Calculate the intercepts:

  • Y-intercept: Set x=0x = 0. f(0)=03+3(0)2+2=2f(0) = 0^3 + 3(0)^2 + 2 = 2 So, the yy-intercept is (0,2)(0, 2).

  • X-intercepts: Solve f(x)=0f(x) = 0. x3+3x2+2=0x^3 + 3x^2 + 2 = 0 This can be solved either by factoring or using numerical methods.

3. Determine
