A rational function is a mathematical function that can be expressed as the ratio of two polynomial functions. It can be written in the form f(x) = p(x)/q(x), where p(x) and q(x) are both polynomial functions and q(x) is not equal to 0. What is the domain of a rational fu...

Example 2: Find the domain of f(g(x)) with respect to the functions from Example 1. Solution: Finding the domain of the inner function (g(x)): Since g(x) = 5 - x is a polynomial, it defined everywhere, the domain of inner function = the set of all real numbers = R Finding ...
Example: finding the quotient of two functions 1.find (f/g)(x) and state the restrictions on the domain if f(x) = (x+4)(x-7) and g(x) = 2(x +4) Step 1: Divide one function by the other to get the quotient of the two functions. (f/g)(x) = f(x)/g(x) By dividi...

The purpose of this study was to investigate students’ misconceptions in the process of finding domain of a composite function. The participants were 1500 engineering students in a state university in Istanbul, Turkey. The Calculus course is required course for all engineering students. Data analysis...
Local minimum is the point in the domain of the functions, which has the minimum value. The local minimum can be computed by finding the derivative of the function. The first derivative test, and the second derivative test, are the two important methods of finding the local minimum for a ...
In the case of sine functions, the parent function is sin(x), and its period is 2 pi. How do you find the period of a sine wave? To find the period of a sine wave with equation f(x) = sin(Ax), use the formula Period = 2pi/|A|. If |A| = 1, then the period of the ...
