Every element has an inverse: We will discuss dividing polynomials, finding zeroes of polynomials and sketching the graph of polynomials. Solving Exponential Equations — In this section we will discuss a couple of methods for solving equations that contain exponentials. The red circles indicate open circles.
The number of dimes that Matt has. Again, notice that the general term of the sequence is linear and that the constant difference - 3 is the coefficient of the variable.
What needs to be found. We then evaluate the expression following the correct order of operations, of course, to find the output, what f 2 is equal to. It looks like the vertical lines may touch two points on the graph at the same time.
Any common factors in the numerator and denominator of the answer will automatically be cancelled out. Since the difference between ANY two consecutive terms is a constant, the sequnce is arithmetic. If T denotes the range off, then by previous definition T consists of all numbers of the form f a where a is in R.
Show that the ratio of ANY two consecutive terms in the sequence is a constant. We will discuss factoring out the greatest common factor, factoring by grouping, factoring quadratics and factoring polynomials with degree greater than 2.
This is shown in the second line, where the x has been replaced by 2. A polynomial function is a function that is defined by a polynomial, or, equivalently, by a polynomial expression.
Why do you think it is called a discontinuous function. Common Graphs - In this chapter we will look at graphing some of the more common functions you might be asked to graph.
Determine what is known and what needs to be found what is unknown. I've labeled the steps so that you better understand the explanation below. We will concentrate on solving linear inequalities in this section both single and double inequalities.
In this section we will be looking at vertical and horizontal shifts of graphs as well as reflections of graphs about the x and y-axis. Collectively these are often called transformations and if we understand them they can often be used to allow us to quickly graph some fairly complicated functions.

How long would it take. While a function doesn't necessarily have to use numbers, this is a math class, so the rest of the examples we'll look at will involve numbers - like these for example: x 2 + 1 and 3(x - 1. Function notation is used to indicate that one variable, "f(x)", is a function of the other variable, "x".
Write a function using the information given in the word problem. Next, evaluate the function with specific values for the variable by plugging, or substituting, in the value and solving.
