Math Problem Statement
Starting with the graph of a basic function, graph the following function using the techniques of shifting, compressing, stretching, and/or reflecting. Be sure to identify at least three key points. Find the domain and range of the function.
g left parenthesis x right parenthesis equals left parenthesis x plus 4 right parenthesis cubed plus 6g(x)=(x+4)3+6
Solution
To graph the function , let's follow the process of shifting, stretching, compressing, and reflecting starting with the graph of the basic cubic function .
Step-by-Step Graphing Process:
-
Start with the base function: The base function is , which is a standard cubic curve that passes through the origin with the following key points:
It has an "S" shape, with increasing behavior for and decreasing for .
-
Shift left by 4 units: The term means we shift the graph of 4 units to the left. So, the key points are now:
- (formerly )
- (formerly )
- (formerly )
-
Shift up by 6 units: The at the end means we shift the entire graph up by 6 units. The key points after this shift are:
Domain and Range:
-
Domain: The domain of is the set of all real numbers since a cubic function is defined for all . Hence, the domain is .
-
Range: The range of is also all real numbers, as the cubic function takes on all values from negative infinity to positive infinity. Thus, the range is .

- What if the function was ? How would the range be affected?
- What are the inflection points of the basic cubic function ?

- Can you generalize the transformation for a function ?
Tip: Always shift horizontally first before performing any vertical transformations when dealing with function transformations.
