# How do you find vertical, horizontal and oblique asymptotes for #f(x) = (5x-15 )/ (2x+14)#?

##### 1 Answer

Vertical asymptote = x = -7, Horizontal asymptote = y = 5/2, no oblique asymptotes.

#### Explanation:

An ASYMPTOTE is a line that approches a curve, but NEVER meets it.

To find the **vertical asymptote** , put the denominator = 0 (because 0 cannot divide any number) and solve.

Given below is the step-by-step walk through

The curve can never touch x = -7, thus making it the vertical asymptote.

To find the **horizontal asymptote** , compare the degree of the expressions in the numerator and the denominator.

Here, the degree of the numerator = 1 and the degree of the denominator = 1.

Since the degrees are equal, the horizontal asymptote

The **oblique asymptote** is a line of the form y = mx + c.

In other words,

*degree of numerator = degree of denominator + 1*

Here, the degree of the numerator = degree of the denominator.

Therefore, the given function has no oblique asymptotes.

The graph for the function is given below:
