(y^2)/(21)-(x^2)/(13)=1

\frac{y ^{2}}{21} - \frac{x ^{2}}{13} = 1

(h, k) = (0, 0), a = 21, b = 13

Solution steps

\frac{y ^{2}}{21} - \frac{x ^{2}}{13} = 1

Rewrite

\frac{y ^{2}}{21} - \frac{x ^{2}}{13} = 1

in the form of a standard hyperbola equation

\frac{( y - 0 ) ^{2}}{( 21 ) ^{2}} - \frac{( x - 0 ) ^{2}}{( 13 ) ^{2}} = 1

Therefore Hyperbola properties are:

(h, k) = (0, 0), a = 21, b = 13

8 x^{2} - 15 = 4 y^{2} + 1

\frac{x ^{2}}{400} - \frac{y ^{2}}{441} = 1

11 x^{2} - 7 y^{2} + 44 x - 56 y - 145 = 0

25 x^{2} - 64 y^{2} + 100 x - 256 y - 1756 = 0

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