16x^2+9y^2=144

16 x^{2} + 9 y^{2} = 144

(h, k) = (0, 0), a = 3, b = 4

Solution steps

16 x^{2} + 9 y^{2} = 144

Rewrite

16 x^{2} + 9 y^{2} = 144

in the form of the standard ellipse equation

\frac{( x - 0 ) ^{2}}{3 ^{2}} + \frac{( y - 0 ) ^{2}}{4 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (0, 0), a = 3, b = 4

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (0, 0), b = 4, a = 3

f (x) = x^{2} - 3 x + 2

f (x) = x^{2} + 3 x - 4

x^{2} + 4 y^{2} = 16

y^{2} = - 28 x

\frac{x ^{2}}{5} + \frac{y ^{2}}{9} = 1
