Question

Use a table to compress the function y= f (x) vertically by a factor of 1/2. Identify the graph of the function and its transformation.The first graph is the original.

Answer 1

First, let's identify some points of the original graph. Then, to find the compressed graph, we need to multiply the y-coordinates by 1/2.

So we have:

`\begin{gathered} A(-3,0)\\ \\ B(-2,5)\\ \\ C(1,0)\\ \\ D(4,2)\\ \\ \\ \\ A^(\prime)(-3,0)\\ \\ B^(\prime)(-2,2.5)\\ \\ C^(\prime)(1,0)\\ \\ D^(\prime)(4,1) \end{gathered}`

The graph that has these compressed points above is the graph from the fourth option
