Suppose that g(x) = f(x) + 2. Which statement best compares the graph of g(x) with the graph of f(x)?
A. The graph of g(x) is shifted 2 units down.
O B. The graph of g(x) is vertically stretched by a factor of 2.
C. The graph of g(x) is shifted 2 units to the right.
D. The graph of g(x) is shifted 2 units up.

2 units up

Step-by-step explanation:

You have no stretch because no number in front and nothing is done to x do no movement to the sides

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,
