What happens when you introduce a substitution in solving an equation?

• You simplify the original problem

• You ignore the original problem

• You create a new problem to solve

• You solve the original problem directly

What does it mean if an equation has no real solutions?

• The equation is incorrect

• The solutions are imaginary

• The equation is unsolvable

• The solutions are infinite

What is the term used to describe a parabola that is always above the x-axis?
