This section is a sample of what you will be learning based on the chapters that you have purchased, bought and paid for.

Choosing whichever chapter(s) you are weak in, is the best way to improve.

Here we show you as an example of what you will get in the form of questions, explanations and workings from our tailored lessons in pre-recorded teaching video(s).Â

*f* is given by f(*x*) = *a*(*x* – *p*)Â² + *q*, where *a*, *p* and *q* are constants. If f(3) = 5, f(*p*) = -3 and

f(*q*) = 29, find the possible values of *a*, *p* and *q*.

If 2*x*Â² – *qx* + 2 > 0 for all values of *x*, show that *q* < -4 or *q* > 4.

by + m +1 = x

$m({x \over y}) + b^2({y \over x}) + 8 = 0$

Find the values of *b* and the corresponding values of *m*.

Evaluate $5 ^{2 log_53}$

The diagram shows the graph of $y \over x$ against $x$.

Express $y$ in the form of $y = ax^2 + bx + c$, and state the numerical values of $a$, $b$ and $c$.

Find a vector of magnitude 2 units in the direction of AB, where A (2, -3) and B (-1, 1).
