For certain functions (and only those!), there is a relationship between stretching along the y-axis and shrinking along the x-axis and vice-versa. Let's consider the function f(x) = x². (a) Write the equation of f(x) x² stretched vertically by a factor of m. (b) Write the equation of f(x) = x² stretched horizontally by a factor of n.

For certain functions (and only those!), there is a relationship between stretching along the y-axis and shrinking along the x-axis and vice-versa. Let's consider the function f(x) = x?. (a) Write the equation of f(x) = x² stretched vertically by a factor of m. (b) Write the equation of f(x) = x² stretched horizontally by a factor of n. (c) In order to have the functions in parts (a) and (b) be the to equal in terms of m? same, what does n have (d) Therefore, we can say that vertically stretching y same as horizontally stretching y = x² by what amount? x² by a factor of m is the
