Question

Your friend graphs the function represented by the input-output table. Is your friend correct? Explain your reasoning.

Answer 1

From the above input-output diagram, the ordered pairs are $(-4,-1)(-2,1)(0,3)(2,5)$.

And from the above graph, the ordered pairs are $(-1,-4)(1,-2)(3,0)(5,2)$.

We can see friend takes $\mathrm{x}$-axis on $\mathrm{y}$-axis and $\mathrm{y}$-axis on $\mathrm{x}$-axis in the graph,

i.e., friend take $\mathrm{x}$ coordinate and plot it on $\mathrm{y}$- axis.

Hence, friend is not correct.
