Which of the following are possible equations of a parabola that has no real solutions and opens downward?

y = ( x - 4) 2 + 2
y = -( x + 4) 2 - 2
y = -( x - 4) 2 - 2
y = -x 2 - 2
y = -( x + 4) 2 + 2

F(x)=x^3+4 question 6 options: the parent function is shifted up 4 units the parent function is shifted down 4 units the parent function is shifted left 4 units the parent function is shifted right 4 units
