Which statements about the graph of the function f(x) = -x2 - 4x + 2 are true? Select three options,
The domain is {x\x 5-2}.
The range is fyly s6}.
The function is increasing over the interval (-00, -2).
The function is decreasing over the interval (-4,co).
The function has a positive y-intercept.

I’m sure you could google it. my profile picture might

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
