# Transformation of functions question watch

1. Is a stretch parallel to the x-axis by SF sqrt(C) followed by a stretch parallel to the y-axis by SF sqrt(C) equivalent to an enlargement about the origin by SF C?

Is a stretch parallel to the x-axis by SF sqrt(C) followed by a stretch parallel to the y-axis by SF sqrt(C) equivalent to a stretch parallel to the line y=x by SF C?

order does not matter in fact look at the "multiplication" below

| √c 0 | | 1 0 |
| 0 1 | | 0 √c|
