How would you shift the parent function y=x squared to graph the function (x-4)squared +5

Pls! does anybody know a shortcut for answering these types of questions in the future?

Which of the following equations is of the parabola whose vertex is at (4, 3), axis of symmetry parallel to the y-axis and focus at (4, -3)? a.) y+3=1/24 (x+4)^2 b.)y-3=-1/24 (x-4)^2 c.)x-4=-1/24 (y-3)^2

Determine which expressions represent real numbers and which expressions represent complex number. asaaap! plis!
