How do you determine the equation of a parabola in standard form with a vertex at (3, 4) passing through the point (5.4)?

There is no such parabola.

Explanation:

The vertex represents either the maximum or minimum value of the parabola and has form #(h,k)#. The horizontal line #y=k# intersects the parabola in exactly one point: at the vertex. Since one of your points is the vertex, and has #y#-coordinate #4#, the line #y=4# only intersects the parabola at only that point. Since the other point is #(5,4)#, with #y#-coordinate 4, that point cannot be on the parabola.
