Transcript text: How can you create a graph that reflects the cubic function across the $y$-axis?
Add -1 to each $x$-value.
Add -1 to each $y$-value.
Multiply each y-value of a function by -1.
Multiply each $x$-value of a function by $\mathbf{- 1}$.
Solution
Solution Steps
Step 1: Reflection across the y-axis
To reflect a graph across the y-axis, we need to negate the x-values. This means that for every point (x, y) on the original graph, the reflected point will be (-x, y).
Step 2: Applying the reflection to the function
Let the cubic function be represented as f(x). To reflect the graph across the y-axis, we need to replace x with -x. The reflected function is denoted as f(-x).
Step 3: Choosing the correct option
The question asks how to create a graph that reflects the cubic function across the y-axis. We have determined that this involves replacing x with -x. Therefore, we need to multiply each x-value of the function by -1.
Final Answer
\\(\boxed{\text{Multiply each } x \text{-value of a function by } -1.}\\)
