Math Problem Statement
Graph the following function by moving the green and blue dots (if necessary). y, equals, cube root of, x, minus, 5, end cube root, minus, 5 y= 3
x−5 −5
Solution
It seems you're dealing with a graphing problem involving the function:
Let’s break down how to graph this function by transforming it step-by-step:
Step 1: Understand the Base Function
The base function is the cube root function, . This function has a characteristic shape:
- The graph of passes through the origin (0,0).
- It increases from left to right, and is symmetric about the origin.
Step 2: Transformations
Now, let’s apply the transformations to the base function.
-
Horizontal Shift:
- The expression inside the cube root is .
- This results in a horizontal shift to the right by 5 units.
- So, the graph now starts from the point .
-
Vertical Shift:
- There is also a -5 outside the cube root, meaning the entire graph shifts down by 5 units.
- The starting point now moves from to .
Step 3: Plotting Key Points
To plot the graph, consider these points:
- Starting Point: The shifted version starts at .
- Additional Points: Calculate a few values to understand the behavior:
- When , .
- When , .
Graph Description
- The graph will have an inflection point at .
- To the right of , the graph gradually increases.
- To the left, the values of continue to decrease, but at a decreasing rate.
Moving the Dots (Green and Blue)
- Green Dot: Move it to the point to mark the new "origin" after the transformation.
- Blue Dot: Use it to mark any other point that helps illustrate the increasing nature, for example, .
Would you like more detailed instructions on how to perform these transformations or see a graph of this function?
Questions for Further Exploration:
- What are the differences between the graphs of cube root functions and square root functions?
- How does a horizontal shift affect the domain of a function?
- What happens if we have a negative coefficient in front of the cube root?
- Can you determine the range of this transformed function?
- How would the graph change if the transformation was ?
Tip: When graphing transformed functions, it’s helpful to first sketch the base function and then apply each transformation one by one.
