Find the intercepts and domain and perform the symmetry test on each parabola with equation: rcises 12.4 plete the following: a) y2 = 8x c) y2 = - 4x (b) x2 = 8y (d) x = - 4y

Respuesta :

Expression

[tex]\begin{gathered} y^2=-4x \\ y=\sqrt[]{(-4x)} \end{gathered}[/tex]

intercepts

x-intercept (when y = 0)

x = 0

y-intercept (when x = 0)

y = 0

domain

x = all negative numbers

Symmetry

Yes, it is symmetry over y = 0
