We have a function and with some simple operations we can shift the function along the x- and y-axes and also scale it (shrink and enlarge it). If it crosses more than once it is still a valid curve, but is not a function.. Our premium worksheet bundles contain 10 activities and answer key to challenge your students and help them understand each and every topic within their grade level. The difference between a function and a relation is that a function has exactly one output value (from the range) for every input value (from the domain). This is the currently selected item.
