Types of Functions
Functions are mathematical expressions that relate a set of inputs to a set of outputs. There are several types of functions, each with its own unique characteristics and applications.
Linear Functions
- A linear function is a function whose graph is a straight line.
- The equation of a linear function is y = mx + b, where m is the slope and b is the y-intercept.
Quadratic Functions, Choose the function whose graph is given by:
- A quadratic function is a function whose graph is a parabola.
- The equation of a quadratic function is y = ax^2 + bx + c, where a, b, and c are constants.
Exponential Functions
- An exponential function is a function whose graph is a curve that increases or decreases rapidly.
- The equation of an exponential function is y = a^x, where a is a constant.
Logarithmic Functions
- A logarithmic function is the inverse of an exponential function.
- The equation of a logarithmic function is y = log a(x), where a is a constant.
Trigonometric Functions
- Trigonometric functions are functions that relate the angles of a triangle to the lengths of its sides.
- The most common trigonometric functions are sine, cosine, and tangent.
FAQ Overview: Choose The Function Whose Graph Is Given By:
What is the difference between a linear and a quadratic function?
Linear functions have a constant rate of change, while quadratic functions have a rate of change that changes at a constant rate.
How do I find the domain and range of a function?
The domain is the set of all possible input values, and the range is the set of all possible output values.
What is the significance of the y-intercept of a function?
The y-intercept is the point where the graph of the function crosses the y-axis, and it represents the value of the function when the input is zero.
