Question
The graph of the parent function, f(x) = x3, is translated such that the function g(x) = (x – 4)3 – 1 represents the new graph. Which transformations occurred?
Horizontal translation:
Vertical translation:
Solution
Horizontal translation:
The function g(x) = (x – 4)³ – 1 is a horizontal translation of the parent function f(x) = x³. The "- 4" inside the parentheses indicates a shift to the right by 4 units.
Vertical translation:
The "- 1" outside the parentheses in the function g(x) = (x – 4)³ – 1 indicates a vertical translation of the parent function f(x) = x³. This represents a shift downward by 1 unit.
Similar Questions
To determine which transformation changes the graph of \( f(x) = x^4 \) to the graph of \( g(x) = (x - 3)^4 - 2 \), we need to understand how transformations affect the graph of a function. 1. **Horizontal Translation**: - \( f(x - h) \) translates the graph of \( f(x) \) to the right by \( h \) units. - \( f(x + h) \) translates the graph of \( f(x) \) to the left by \( h \) units. 2. **Vertical Translation**: - \( f(x) + k \) translates the graph of \( f(x) \) up by \( k \) units. - \( f(x) - k \) translates the graph of \( f(x) \) down by \( k \) units. Given \( g(x) = (x - 3)^4 - 2 \): - The term \( (x - 3) \) indicates a horizontal translation to the right by 3 units. - The term \( -2 \) indicates a vertical translation down by 2 units. So, the correct transformation is: - Translate the graph of \( f(x) = x^4 \) to the right by 3 units. - Then translate it down by 2 units. This matches option **B**: - Translating it to the right by 3 units, then translating it down by 2 units. Therefore, the correct answer is **B**.
