Solve for x:
Take the root of both sides and solve.
All real numbers Interval Notation
(-infinity, infinity)
(Don’t actually write infinity, write the infinity symbol)
We have the following functions:
f (x) = x3 - 3x2 - 13x + 15
f (x) = x4 + 3x3 - 8x2 + 5x - 25
f (x) = x3 - 2x2 - x + 2
f (x) = -x3 + 13x - 12
Factoring we have:
f (x) = x3 - 3x2 - 13x + 15 -------> x + 3
f (x) = x4 + 3x3 - 8x2 + 5x - 25 -> x + 5
f (x) = x3 - 2x2 - x + 2 ------------> x - 2
f (x) = -x3 + 13x - 12 -------------> x + 4
Ok. This is called a Coordinate Plane (aka line plots). Your teacher is asking to find the number on those plots.
You have your X and Y axis.
You go over to X before going to Y
So I work my way up so your first one is
1,2
Second is
-2,4
Third is
2,6
and the last one (the top plot)
1,8
Hope this helped!
Brainiest please!
The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
I am unable to read all of the options in the picture you provided but I hope this helps! (:
