The parabola y=x^2y=x 2 y, equals, x, squared is scaled vertically by a factor of \dfrac{5}{2} 2 5 start fraction, 5, divided by, 2, end fraction. What is the equation of the new parabola? y=

Step-by-step explanation:

y=x²

5/2 y=(5/2x)²

y=25/4 x²×2/5=5/2 x²

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,
