Which statements about the graph of the function f(x) = -x2 - 4x + 2 are true? check all that apply. um the domain is {x\x s-2} the range is {yly s 6). the function is increasing over the interval (-0, -2) the function is decreasing over the interval (- the function has a positive y-intercept.

answer:

c) the x-coordinate of the center of the circle increases by 3

b

step-by-step explanation:

i dont know

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
