Math Problem Statement

Use transformations of the standard cubic function, f(x) = x^3, to graph the function h(x) = -(x + 3)^3.

Solution

The given task asks us to use transformations of the standard cubic function f(x)=x3f(x) = x^3 to graph the function h(x)=(x+3)3h(x) = -(x + 3)^3.

Here’s how we can break down the transformations:

1. Start with the basic cubic function:

f(x)=x3f(x) = x^3 This is the standard cubic function.

2. Horizontal Shift:

The expression (x+3)(x + 3) indicates a horizontal shift. Since it is (x+3)(x + 3), the graph of f(x)=x3f(x) = x^3 is shifted 3 units to the left. The new equation becomes: f(x)=(x+3)3f(x) = (x + 3)^3

3. Vertical Reflection:

The negative sign in front of the cubic term, (x+3)3-(x + 3)^3, indicates a vertical reflection. This reflects the graph over the x-axis. The graph is now: h(x)=(x+3)3h(x) = -(x + 3)^3

Final Graph:

The graph of h(x)=(x+3)3h(x) = -(x + 3)^3 is obtained by taking the standard cubic graph, shifting it 3 units to the left, and reflecting it over the x-axis.

Would you like further explanation on any specific transformation?

Here are 5 related questions:

  1. How do horizontal and vertical transformations differ in cubic functions?
  2. What happens if we add a vertical shift to h(x)=(x+3)3h(x) = -(x + 3)^3?
  3. How would the graph change if we had h(x)=(x+3)3h(x) = (x + 3)^3 instead of the negative sign?
  4. How do you reflect a function across the y-axis versus the x-axis?
  5. What is the effect of compressing or stretching the graph of a cubic function?

Tip: Always apply horizontal shifts before vertical transformations when analyzing function changes!
