A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

A quadratic function is a noun. The plural form would be quadratic functions.

Why is a quadratic function called a quadratic function?

A quadratic function is a second degree polynomial, that is, is involves something raised to the power of 2, also know as squaring. Quadratus is Latin for square. Hence Quadratic.

What is the origin of the quadratic formula?

The quadratic formula is derived by completing the square. That is as much as I can tell you.

How can you use a graph to find zeros of a quadratic function?

The zeros of a quadratic function, if they exist, are the values of the variable at which the graph crosses the horizontal axis.

What is the formula for quadratic function?

f(x) = ax^2 + bx + c, where a != 0 (for obvious reason: it wouldn't be a quadratic function)

How can you determine if a function is a quadratic function from its equation?

If the highest exponent of independent variable(say x) is 2 and the highest exponent of dependent variable(say y) is 1 and x and y are not multiplied, then the function is quadratic. For example: 3x-y+x2= 2y-5x+7 represents a quadratic function but y= xy+x2+5 doesn't represent a quadratic function.

Is the inverse of an exponential function the quadratic function?

No. The inverse of an exponential function is a logarithmic function.

What is the difference between quadratic function and quadratic formula?

A quadratic function is a function where a variable is raised to the second degree (2). Examples would be x2, or for more complexity, 2x2+4x+16. The quadratic formula is a way of finding the roots of a quadratic function, or where the parabola crosses the x-axis. There are many ways of finding roots, but the quadratic formula will always work for any quadratic function. In the form ax2+bx+c, the Quadratic Formula looks like this: x=-b±√b2-4ac _________ 2a The plus-minus means that there can 2 solutions.

Who derived the quadratic equation formula?

Quadrasies, in fifth century Greece.
