Describe the surface. z = 6 − y2 cone ellipsoid hyperboloid elliptic cylinder hyperbolic cylinder parabolic cylinder elliptic paraboloid hyperbolic paraboloid

The equation doesn't include variable x, so the equation represents some type of cylinders.

Since is equation of parabola, then this is  parabolic cylinder (see attached diagrams for details).

parabolic cylinder

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 is shifted from its position in all the four options.
