x=-2 represents a vertical line so that a perpendicular line to it will be a perfectly horizontal line passing through (2,1). A perfectly horizontal line has slope m=0 (it is not increasing nor …

To graph this we will draw a vertical line at #-4# on the horizontal axis. The line will be a solid line because the inequality operator contains an "or equal to" clause.

The asymptotes are x=3 and y=x-5 An asymptote is defined as a line or curve that another line or curve approaches, but never meets. As such, we simply find the values of x and y that the y …

A line segment is bisected by a line with the equation # - y + 4 x = 3 #. If one end of the line segment is at # ( 2 , 6 )#, where is the other end? GeometrySpecial Properties and Parts of …

As you can see the shell method isn't as intuitive as the disc method. This method takes a fair amount of study to get comfortable with. The main use of this method is when it isn't possible …

2017年8月12日 · In projectile motion, we can treat the horizontal and vertical directions separately. Doing so in this case leads to the answer u_x=36.4 ms^-1. Let's summarise what …

How do you tell whether the graph opens up or down, find the vertex, and find the axis of symmetry given #y=-x^2-1#?

Explanation: The denominator of f (x) cannot be zero as this would make f (x) undefined. Equating the denominator to zero and solving gives the values that x cannot be and if the numerator is …

The vertical assymptote is x = 7 and the horizontal assymptote is y = 1 Vertical assymptotes are the lines of the type x = a that the function can never take because doing so will create a math …
