Graph the function y = x + 3x2 - x - 3. Which lists all of the turning points of the graph rounded to the nearest
whole number?

(-3,0) and (1,0)
(-2,3) and (0, -3)
(-2,3), (-1,0), and (0, -3)
(-3,0), (-1,0), and (1,0)

I believe it's (-2,3), (-1,0), and (0,-3)

Step-by-step explanation:

y = x + 3x2 - x - 3 = y = 3x^2 - 3

I used desmos.com/calculator and mathpapa.com/algebra-calculator.html (I highly suggest using these sites. They tell you how to solve it step-by-step.)

one that is bigger than 3 1/2

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,
