What is the domain and range of a quadratic function?
The domain and range can be the whole of the real numbers, or some subsets of these sets.
How many real solutions can the quadratic formula give?
A quadratic equation can have either two real solutions or no real solutions.
What happens in the quadratic formula that yields no real solutions?
If the discriminant of b2-4ac in the quadratic equation formula is less than zero then the equation will have no real roots.
What is the use of quadratic formula if it is not used into real life?
The question is based on the false assumption that the quadratic formula is not used in daily life. Wrong, it IS!
What are some real life situations that would use the quadratic formula?
As you probably suspect, there are no non-mathematical situations in which you would use the quadratic formula.
What are the domain and range of the quadratic parent function?
The domain is all real numbers, and the range is nonnegative real numbers (y ≥ 0).

How many real solutions can the quadratic formula give?
A quadratic equation can have either two real solutions or no real solutions.
What is the range of the quadratic parent y equals x squared?
All real numbers that are greater than or equal to zero
What happens in the quadratic formula that yields no real solutions?
If the discriminant of b2-4ac in the quadratic equation formula is less than zero then the equation will have no real roots.
Is the range for all quadratic functions the same as the domain?
No. The domain is usually the set of Real numbers whereas the range is a subset comprising Real numbers which are either all greater than or equal to a minimum value (or LE a maximum value).
What is the graph of a quadratic formula?
In general, quadratic equations have graphs that are parabolas. The quadratic formula tells us how to find the roots of a quadratic equations. If those roots are real, they are the x intercepts of the parabola.
What is the use of quadratic formula if it is not used into real life?
The question is based on the false assumption that the quadratic formula is not used in daily life. Wrong, it IS!
When can a quadratic function have an inverse?
It depends on the domain and codomain. In complex numbers, that is, when the domain and codomain are both C, every quadratic always has an inverse.If the range of the quadratic in the form ax2 + bx + c = 0 is the set of real numbers, R, then the function has an inverse if(a) b2 - 4ac ≥ 0and(b) the range of the inverse is defined as x ≥ 0 or x ≤ 0
What are some real life situations that would use the quadratic formula?

How do you solve complex cases of quadratic equations?
If the discriminant - the part under the radical sign in the quadratic formula - is negative, then the result is complex, it is as simple as that. You can't convert a complex number to a real number. If a particular problem requires only real-number solutions, then - if the formula gives complex numbers - you can state that there is no solution.
What statement must be true of an equation before you can use the quadratic formula to find the solutions?
The quadratic formula can be used to find the solutions of a quadratic equation - not a linear or cubic, or non-polynomial equation. The quadratic formula will always provide the solutions to a quadratic equation - whether the solutions are rational, real or complex numbers.
