h(x)h(x)=-5x^2+10x+15

Lösung

h (x) h (x) = - 5 x^{2} + 10 x + 15

Lösung

(h, k) = (1, 0), a = 2, b = 25

Schritte zur Lösung

yy = - 5 x^{2} + 10 x + 15

Rewrite

yy + 5 x^{2} - 10 x - 15 = 0

in the form of the standard ellipse equation

\frac{( x - 1 ) ^{2}}{2 ^{2}} + \frac{( y - 0 ) ^{2}}{( 2 5 ) ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (1, 0), a = 2, b = 25

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (1, 0), b = 25, a = 2
