What do you think the graph ... graph has not moved up or down maximum turning point when \(y = 1\) and minimum turning point when \(y = - 1\) The graph looks like: Now try the example questions ...

Unfortunately, this is not always the case ... in these figures is blatant. In other examples, the distortion may be more subtle. For example, some graph designers label the bars in bar graphs ...

Instead of writing Function = multiply by 3 we can use algebra. Graphically, \(f(x) = x^2\) is the same as the graph of \(y = x^2\). Writing graphs as functions in the form of \(f(x)\) is useful ...
