The parabola f(x)=(x-2)2 + 1 is graphed in the xy-coordinate plane. What is true about the vertex of the parabola? A It is 2 units to the left of the origin and 1 unit down from the origin. B. It is 2 units to the right of the origin and 1 unit up from the origin. C. It is 2 units up from the origin and 1 unit to the right of the origin. D. It is 2 units down from the origin and 1 unit to the left of the origin.​

the answer is d

step-by-step explanation:

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

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,
