The graph of a quadratic function, y=x^2, is reflected over the x-axis. which of the following is the equation of the transformed graph?

Whenever a function is reflected over the x-axis, we can replace y with -y. This is true for any function.

Let's do this to the function .

This is the equation of the transformed graph.

ANSWER:

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
