Quadric functions q and w are graphed on the same coordinate grid. the vertex of graph of q is 18 units below the vertex of the graph of w.

which pair of functions could have been used to create the graph of q and w?
A q(x)18x^2 and w(x)=x^2
B q(x)=x^2+18 and w(x)=x^2
C q(x)=-18^2 and w(x)=x^2
D q(x)=x^2-18 and w(x)=x^2

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

the 4th choice is the correct one
