MAT 170 is generally a Pre-calculus class, a class which you might have to take before Calc I/II for understanding the basics. This course focuses on developing skills to understand and describe the behavior of linear, exponential, logarithmic, polynomial, rational, and trigonometric functions. The following is a detailed description of the concepts involved in MAT 170 :

### 1) Linear Functions

As per Columbia.edu, the linear function is popular in economics. It is attractive because it is simple and easy to handle mathematically. It has many important applications. Linear functions are those whose graph is a straight line. A linear function has the following form y = f(x) = a + bx. It has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.

Linear functions are one of the easiest and important topics you may study in MAT 170. Try to score well as this is the bonus you can get and many of you would have studied Linear functions in high school so it won’t be a big problem.

### 2) Exponential Functions

As per Math Lumar, Exponential functions are those function whose value is a constant raised to the power of the argument, especially the function where the constant is e. If b is any number such that and then an exponential function is a function where b is called the base and x can be any real number.

Exponential functions are something where a constant is raised to the power of ‘e’. They are generally equations which you can solve graphically or algebrically. These exponential functions are a little bit similar to the linear functions and also of the same difficulty level like the linear functions so score as much as you can on this topic too.

### 3) Trigonometric Functions

In mathematics, As per Wikipedia, the trigonometric functions (also called circular functions, angle functions or goniometric functions) are functions of an angle. They relate the angles of a triangle to the lengths of its sides. The most familiar trigonometric functions are the sine, cosine, and tangent.

Trigonometric functions may be something new to you because you might not have studied this topic in your high school so it might be difficult to understand in the beginning. This topic is something that if you get the grip on it, you’ll love studying it but sometimes trig becomes the one that decreases your GPA. Try harder and harder and try your best.

### 4) Logarithmic functions

As per Math Lumar, The logarithmic function is defined as the inverse of the exponential function. For B > 0 and B not equal to 1, y = LogBx is equivalent to x = B y. Note: The logarithm to the base e is written ln(x).

A logarithmic function might be new to you and this topic is a bit challenging. Try to look up at youtube videos for it or go to the tutoring center because there are chances you may not get in a concept in one lecture. But never lose hope and work the best you can.

### 5) Polynomial functions

As per the Math center of UK, a polynomial function is a function such as a quadratic, a cubic, a quartic, and so on, involving only non-negative integer powers of x. We can give a general definition of a polynomial, and define its degree.

A polynomial function may be complex and a bit tough. They are generally tough equations to solve. They involve complex problem solving and the equation solving due to many big powers and numbers. Give it some more time and hard work as it is an integral part of MAT 170.

MAT 170 is the pre-calculus class that sets you up to understand the basics . It is one of the easiest courses taken at Arizona State University and you will find taking this course. Students taking this course will improve their problem-solving abilities and know how to make logical and verbal arguments.
