The graph of a quadratic function contains the points (1, 9), (0, 0), and (–1, 9). shawn thinks the function f(x) = x2 was vertically stretched by a factor of 9. brielle thinks the function f(x) = x2 was horizontally shrunk by a factor of 3. determine who is correct and explain why

Both Shawn and Brielle are correct. The function that represents a vertical stretch by a factor of 9 is f(x) = 9x2. The function that represents a horizontal shrink by a factor of 3 is

f(x) = (3x)2, which is equal to f(x) = 9x2.

Additionally, if you wanted to verify that the given points are on the graph of both functions, you could substitute them into the functions to get true statements.

this is the correct answer, the other person is incorrect. (edunuity)

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
