Final answer:
To obtain the graph for the equation y = f(8x), you need to start with the graph of the original function f(x) and dilate it horizontally by a factor of 8.
Step-by-step explanation:
When the equation y = f(8x) is given, it means that the original function f(x) is being evaluated at 8 times the value of x. To obtain the graph for this equation, you need to follow these steps:
Start with the graph of the original function f(x).
Dilate the graph horizontally by a factor of 8, which means stretching it horizontally.
Plot the points on the new graph by choosing different values of x and calculating the corresponding values of y using the dilated function.
Join these points to form the graph of y = f(8x).
