Math Problem Statement
range of f(x)= (x+4) cubed - 5
Solution
The given function is:
To find the range, let's analyze the function step-by-step:
-
The expression represents a cubic function, which has a domain of all real numbers () and a range of all real numbers () because cubic functions increase without bound in both directions.
-
Shifting this cubic function by 4 units to the left () does not affect the range, so the range of is still all real numbers.
-
The next step is the subtraction of 5. Subtracting a constant shifts the entire graph down by 5 units. Thus, the range of is also all real numbers ().
Therefore, the range of the function is:
