# MATH 1111 - College Algebra: 2.4 Graph of Functions

## 2.4 Graph of Functions

At the end of this section students will be able to:

• Test the graph of a function for symmetry
• Determine if a function is even, odd or neither
• Find the x-intercepts and the y-intercept of the graph of a function
• Determine the intervals where a function is increasing, decreasing or constant
• Sketch the graph of a piecewise-defined function
• Use transformations techniques to graph a function
