Step 1
From the figure, we see that AHUP reflected over the y-axis to form A'H'U'P'.
\(\begin{array}{|c|c|}\hline Old\ coordinates\ & New\ coordinates\ \\ \hline A=(2,-4) & A'=(-2,-4)\\ \hline H=(4,-3 & H'=(-4,-3) \\ \hline U=(2,2) & U'=(-2,2) \\ \hline P=(1,1) & P'=(-1,1)\\ \hline \end{array}\)
From the table we see the x coordinates changes sign.
So we can write a formula as \(\displaystyle{\left({x},{y}\right)}\rightarrow{\left(−{x},{y}\right)}\)

Step 2 Answer: Reflection across the y-axis.
Rule is \(\displaystyle={\left({x},{y}\right)}\rightarrow{\left(−{x},{y}\right)}\)

asked 2021-10-19

Let T : \(R^3\) \(\displaystyle\rightarrow\) \(R^3\) be a linear transformation that reflects each vector \(x = (x_1,x_2 ,x_3)\) through the plane \(x_3 = 0\) onto \(T(x) = (x_1,x_2,-x_3)\). Show that T is a linear transformation.
