What is the geometric mean of 7 and 13?

i got up to this step but i don't understand what it's telling me to do in the last step.

  √91 ≈ 9.5394

Step-by-step explanation:

Take the square root of 91 to find the value of x. There is no simpler radical form. You can write it as ...

  x = √91 . . . . . . . simplest radical form

or as

  x ≈ 9.5394 . . . . an approximation of the irrational root

vertical asymptote .

horizontal asymptote .

step-by-step explanation:

given function is .

vertical asymptote is given by setting

denominator =0

when degree of numerator and denominator are same then divide first term of numerator by first term of denominator to get horizontal asymptote.
