the graph of the function f(x) = −3x^2 − 3x + 6 is shown. which statements describe the graph? check all that apply.
a the vertex is the maximum value.
b the axis of symmetry is x = -1/2
c the domain is all real numbers.
d the range is all real numbers.
e the x-intercepts are at (−2, 0) and (1,0).
f the function is decreasing from (−∞, 6.75).

exa:

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

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,
