Here, the domain is all numbers where the denominator is not zero, that is D = R − {3}.

. Draw the sign diagram of the function to understand where the function is above and where it is below the x-axis.

.

So let's look at the choices here.

. . An example would be x=3 for the function f(x)=1/x.

5π, 2. Graphing Stretches and Compressions of y = logb(x) y = log b ( x) When the parent function f (x) =logb(x) f ( x) = l o g b ( x) is multiplied by a constant a > 0, the result is a vertical stretch or compression of the original graph. Asymptotes can be vertical, oblique ( slant) and horizontal.

Let's look at this example: The denominator has two factors.

f(x) has zeros of 1 and 5 [x-intercepts of ( 1, 0 ), ( 5, 0 )]. .

. .

This has a.

Graphing Rational Functions. There are three distinct outcomes when checking for horizontal asymptotes: Case 1: If the degree of the denominator > degree of the numerator, there is a horizontal asymptote at y =0 y = 0. .

The asymptote calculator takes a function and calculates all asymptotes and also graphs the function. When we set them equal to zero. . This is because as 1 approaches the asymptote, even small shifts in the x -value lead to arbitrarily large fluctuations in the value of the function. One reason vertical asymptotes occur is due to a zero in the. .

Removable discontinuities are found as part of the simplification process. Note that the domain and vertical asymptotes are "opposites".

If a graph has a vertical asymptote of x = h, then part of the graph approaches the line x = h without touching it--x is almost equal to h, but x is never exactly equal to h.

Graph y=2tan (4x) and state the vertical asymptotes.
