This document provides examples of how to use WolframAlpha to check work on various algebra topics like graphs, coordinates, factorizing quadratics, completing the square, minimum values of quadratics, solving quadratics and simultaneous equations, and algebraic fractions. It notes that step-by-step solutions require a subscription but WolframAlpha can be used freely for checking answers and generating examples.

1. The examples here show you how to use WolframAlpha for
checking your work and exploring other examples.
Note that step by step solutions are for subscribers only but
WolframAlpha is free to use for an unlimited number of
queries every day so it is great for checking answers or
generating lots of examples.
Examples Part 3

2. Graphs – check the intercept on the y axis

3. Graphs – check the intercept on the y axis

4. Graphs – check the gradient (slope)

5. Graphs – check the gradient (slope)

6. Coordinates

7. Graphs – cubic functions

8. Graphs – reciprocal functions

9. Graphs – power functions

10. Graphs – power functions

11. Factorising Quadratic Expressions

12. Completing the Square
Note, we see that the minimum value of this
function is 1 which happens when x= -3.
You should be able to see why this is the
case from the completed square form.
See next slide also.
