Exponential graphs are graphs in the form \(\text{y = k}^x\). These graphs increase rapidly in the \({y}\) direction and will never fall below the \({x}\)-axis.

What are the underlying principles of how populations change over time? Two basic principles are involved, the idea of exponential growth and its ultimate control. The basics of population ecology ...

As the tangent is a straight line, the equation of the tangent will be of the form \(y = mx + c\). We can use perpendicular gradients to find the value of \(m\), then use the coordinates of P to find ...
