If you know exactly what you are looking for, we recommend jumping straight to using our search engine tool. Use this to hone in on the concepts, topics, or questions you are finding the most difficult. Remember; don&apos;t be afraid if you feel like you need to begin with some of the rudimentary foundations you covered previously in grade 10 math or elsewhere.
Once you have identified the topic you require more work on, our short but informative video lessons wills walk you through examples (from easy to complex problems) to flesh out the concepts you need to learn as well as study tips and strategies. Watch and re-watch these lessons as many times as you need! We also provide a paraphrased transcript on the gist of what was addressed in the video if you prefer to learn and revise this way instead.
Last but certainly not the least of these steps, we encourage you to put your knowledge and skills to the test! We&apos;ve prepared plenty of questions per topic for you to master and perfect! See how well you have learnt and acquire more practice from a wide variety and range (i.e. easy to hard) of questions.

Ex. 1:

Graphing a parabola from vertex form by finding key points

Besides the general form, the vertex form is also another way to express a quadratic function. In this lesson, we will talk about how to find the x-intercepts, y-intercepts, vertex of quadratic functions in vertex form. 

Quadratic function in vertex form: y = a(x-p)^2 + q

Graphing linear functions using table of values

Graphing linear functions using x- and y-intercepts

Graphing linear functions using various forms

Quadratic function in vertex form: y = a(x-p)^2 + q

What You'll Learn

Identify the vertex of a quadratic function directly from vertex form y = a(x-p)² + q

Calculate x-intercepts by setting y = 0 and solving using square roots

Find y-intercepts by substituting x = 0 into the vertex form equation

Apply algebraic techniques to isolate variables and solve quadratic equations

Sketch parabolas by plotting vertex, intercepts, and connecting key points

What You'll Practice

Finding vertices by making both brackets equal zero

Solving for x-intercepts using square root methods with plus-minus signs

Calculating y-intercepts by substituting x = 0

Graphing parabolas using vertex and intercepts
