find the asymptote

Find the asymptote for the hyperbola: \frac{(y+2)^2}{16} - \frac{(x-2)^2}{9} = 1

Solution

The given equation for the hyperbola is:

(y+2)216(x2)29=1\frac{(y+2)^2}{16} - \frac{(x-2)^2}{9} = 1

Standard Form:

This is the standard form of a hyperbola, where the y-term comes first, indicating it is a vertical hyperbola. The general form of a vertical hyperbola is:

(yk)2a2(xh)2b2=1\frac{(y-k)^2}{a^2} - \frac{(x-h)^2}{b^2} = 1

Comparing the equation with the standard form, we can identify the following:

  • h=2h = 2
  • k=2k = -2
  • a2=16a^2 = 16a=4a = 4
  • b2=9b^2 = 9b=3b = 3

Asymptotes:

For a vertical hyperbola, the equations of the asymptotes are given by:

yk=±ab(xh)y - k = \pm \frac{a}{b} (x - h)

Substituting the values of hh, kk, aa, and bb:

y+2=±43(x2)y + 2 = \pm \frac{4}{3}(x - 2)

So, the equations of the asymptotes are:

y+2=43(x2)andy+2=43(x2)y + 2 = \frac{4}{3}(x - 2) \quad \text{and} \quad y + 2 = -\frac{4}{3}(x - 2)

These are the asymptotes for the given hyperbola.
