Question

help please

Answer 1

Derive the equation of the parabola with a focus at (0, 1) and a directrix of y = −1.

f(x) = −one fourth x2

f(x) = one fourth x2

f(x) = −4x2

f(x) = 4x2

Answer 2

B, f(x)=one fourth x2

Answer 3

thx...can i get help 1 more

Answer 4

Derive the equation of the parabola with a focus at (−5, 5) and a directrix of y = -1.

f(x) = −one twelfth (x − 5)2 + 2

f(x) = one twelfth (x − 5)2 + 2

f(x) = −one twelfth (x + 5)2 + 2

f(x) = one twelfth (x + 5)2 + 2
