Web(i) The key fact here is that the square of, for example, $-2$ is the same as the square of $2$. Thus $g (-2)=8-7=1$ and $g (2)=8-7=1$. We have found an $x$ and a $y$, with $x\ne y$, such that $g (x)=g (y)$. (ii) We give two ways of seeing that $g$ is not onto. Let $y=-10$. We show there is no integer $x$ such that $g (x)=y$. WebIn discrete math, we can still use any of these to describe functions, but we can also be more specific since we are primarily concerned with functions that have N or a finite subset of N as their domain. 🔗 Describing a function graphically usually means drawing the graph of the function: plotting the points on the plane. birdrock folding shovel https://pazzaglinivivai.com
