The general form for an exponential equation is $$y = ab^x$$ where $$a$$ is the coefficient, $$b$$ is the base and $$x$$ is the exponent.

Drawing exponential graphs

Maths

In this unit, pupils consider other types of graphs. In the future unit, pupils consider different types of sequences such as Fibonacci and oscillating. Their knowledge is consolidated by linking all prior learning together.

In the prior unit, pupils studied the graphical representation of a geometric sequence and linked features of the graph to its equation. In this unit, other types of graphs are introduced and their key features identified.

Non-linear graphs

The curves are symmetrical about the $$x$$ axis.

The curves are symmetrical about the $$y$$ axis.

Jacob draws the graphs of $$y=2^(-x)$$ and $$y=2^x$$ on the same pair of axes. Which of these statements are correct.

Which of these could be the equation of this curve?

Match each equation to its type of graph.
