Final answer:
The coefficient of x dictates a horizontal stretch in a function.
Step-by-step explanation:
The coefficient of x dictates a horizontal stretch in a function.
When a coefficient other than 1 is multiplied with x in a function, it affects the horizontal stretch or compression of the graph. If the coefficient is greater than 1, it will stretch the graph horizontally, and if the coefficient is between 0 and 1, it will compress the graph horizontally.
For example, consider the function y = 2x. The coefficient 2 will stretch the graph of the function horizontally, making it wider than the graph of y = x.
