(x^2)/4+(y^2)/9 =1

\frac{x ^{2}}{4} + \frac{y ^{2}}{9} = 1

(h, k) = (0, 0), a = 2, b = 3

Solution steps

\frac{x ^{2}}{4} + \frac{y ^{2}}{9} = 1

Rewrite

\frac{x ^{2}}{4} + \frac{y ^{2}}{9} = 1

in the form of the standard ellipse equation

\frac{( x - 0 ) ^{2}}{2 ^{2}} + \frac{( y - 0 ) ^{2}}{3 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (0, 0), a = 2, b = 3

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (0, 0), b = 3, a = 2

\frac{( x - 1 ) ^{2}}{25} + \frac{( y - 3 ) ^{2}}{16} = 1

6 x^{2} + 12 y - 18 = 0

x^{2} + 8 y + 2 x - 23 = 0

\frac{x ^{2}}{9} + \frac{y ^{2}}{4} = 1

f (x) = - 2 x^{2}
