Which statements about the function f(x)=(x-1)(x+7) are true? select
three options.
the vertex of the function is at (-4-15).
the vertex of the function is at (-3,-16).
the graph is increasing on the intervaly> -3.
the graph is positive only on the intervals where y< -7
and where x> 1
the graph is negative on the interval x< -4.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
