The set of ordered pairs (-1, 8), (0, 3), (1, -2), and (2, -7) represent a function. what is the range of the function?
o {x: x=-1, 0, 1, 2}
o {y: y=-7, -2,3,8}
o {x: x = -7, -2,-1,0, 1, 2, 3, 8}
o {y: y = -7, -2,-1, 0, 1, 2, 3,8}

The position of a moving particle is given by the position function: f(t)=-9t-t^2-0.2t^3+0.1t^4 a. at what time does the particle reverse direction? b. when is the displacement positive? (round one decimal place and answer in interval notation) c. when is the displacement negative? (round one decimal place and answer in interval notation) d. when is the particle’s acceleration positive? (round one decimal place and answer in interval notation) e. when is the particle’s acceleration negative? (round one decimal place and answer in interval notation)

Ireally need subtract and simplify.(-y^2 – 4y - 8) – (-4y^2 – 6y + 3)show your work, ! i will mark you brainliest but you have to show your work.

The point a is at –2 and the point b is at 7. marissa would like to divide this line segment in a 4: 3 ratio, and she would like to use the formula x = (x2 – x1) + x1. what values should she substitute into the formula? a = a + b = x1 = x2 =
