Here's a breakdown of some of the questions on tomorrow's test...primarily sections 1.5 to 1.7, some 1.4
- Find (f + g), (f - g), (fg), and/or (f/g) (Combinations of Functions)
- Evaluate (ex: (f + g)(2))
- Compositions of functions
- Use compositions to determine if two functions are inverses
- Find the inverse of a function (switch x, y and solve for y)
- Graph f(x), f inverse, and y=x
- Determine if a function is one-to-one (horizontal line test)
- Shifting of functions
- Linear Regression (Line of Best Fit)
- Find the equation and correlation (r)
- Interpret correlation (strength and direction)
- Solve for y given a value of x
- Solve for x given a value of y
Good luck! I hope you all get an A+!
