I can replace f(x) with x - x^2. Should I plug (x/2) into f(x)? How about (x - 1/2) into f(x)? I need the set up.

A quadratic with no real zeros is a type of quadratic equation where the solutions or roots are imaginary numbers, meaning they involve the square root of a negative number. This type of quadratic cannot be solved using real numbers.
A quadratic has no real zeros if its discriminant, which is the expression under the square root in the quadratic formula, is negative. This means that the solutions will involve imaginary numbers.
Yes, a quadratic with no real zeros can still have solutions, but they will involve imaginary numbers. These solutions can be expressed in the form of a+bi, where a and b are real numbers and i is the imaginary unit.
To graph a quadratic with no real zeros, you can plot points using the x and y values from the solutions involving imaginary numbers. These points will be located on the imaginary axis of the coordinate plane.
Quadratics with no real zeros are commonly used in engineering and physics, particularly in the study of oscillations and vibrations. They can also be used in financial modeling, such as in predicting stock prices or analyzing population growth.
