Which equation represents the parabola shown on the graph?

y2 = 1.5x
x2 = 1.5y
y2 = 6x
x2 = 6y

we know that

The parabola shown on the graph represent a vertical parabola open upward with vertex at the origin

so

the equation of the parabola is equal to

------> equation A

the equation of the directrix is equal to

In this problem we have

the equation of the directrix is equal to

so

the value of a is equal to

substitute the value of a in the equation A

therefore

the answer is the option

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
