Before I answer the question in the title, we need to do some revisions: This is what you do when you solve a quadratic equation like : Solution: => (x-5)(x+2)=0 => If x-5 = 0, then x = 5; if x+2 = 0, then x =-2. The solution is x=5 or x=-2. If you graph…

The domain of a function in x refers to all the possible values of x for which the function is defined. That is, it consist of all the values that make the function exist. Unless otherwise stated, the possible values for the domain is from the set of real numbers. Usually, your teacher will only…

In your study of function, the usual activity you do is to graph the function given an equation. Here is a problem that involve finding the equation given theĀ graphs of functions – linear, quadratic, exponential, and reciprocal (rational) functions. Problem The figure below shows the graphs of common functions. The algebraic representation of the…
