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

What is an inverse of a function?

The opposite of another function - if you apply a function and then its inverse, you should get the original number back. For example, the inverse of squaring a positive number is taking the square root.

Is the cube root of negative number a positive?

No, because the inverse function would not work. Every time you multiply a positive by a positive you get a positive.

What is the relationships between inverse functions?

The inverse of the inverse is the original function, so that the product of the two functions is equivalent to the identity function on the appropriate domain. The domain of a function is the range of the inverse function. The range of a function is the domain of the inverse 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 inverse function of -6?

-6 is a number, not a function and so there is not an inverse function.

What is the inverse of a cubic function?

The inverse of the cubic function is the cube root function.

If an inverse function undoes the work of the original function the original function's becomes the inverse function's domain?

The original function's RANGE becomes the inverse function's domain.

What is the difference between a reciprocal function and an inverse function?

A reciprocal function will flip the original function (reciprocal of 3/5 is 5/3). An inverse function will change the x's and y's of the original function (the inverse of x<4,y>8 is y<4, x>8). Whenever a function is reflected over the line y=x, the result is the inverse of that function. The y=x line starts at the origin (0,0) and has a positive slope of one. All an inverse does is flip the domain and range.

Why negative numbers don't have logarithim?

The logarithmic function is not defined for zero or negative numbers. Logarithms are the inverse of the exponential function for a positive base. Any exponent of a positive base must be positive. So the range of any exponential function is the positive real line. Consequently the domain of the the inverse function - the logarithm - is the positive real line. That is, logarithms are not defined for zero or negative numbers. (Wait until you get to complex analysis, though!)

Why is x squared a inverse function?

X squared is not an inverse function; it is a quadratic function.
