Given p(x), find p(-1) by using synthetic substitution. p(x)=7x^3-6x^2+39x-104

p(-1)=

  p (-1)  = -156

Step-by-step explanation:

Explanation:-

Given polynomial

           p(x)=7x³ -6x²+39x-104

Put x=-1

          p (-1)    = 7 ( -1 )³ - 6 ( -1 )² + 39 (-1 ) - 104

                     = - 7 - 6 - 39 - 104

          p (-1)  = -156

answer: h

step-by-step explanation:

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'.
