Hmm I'll try to unstress. Let's let . This is the same as
So we have the modified version:
Read over this first: Algebra (Math 1314) - Common Graphs - Transformations
So we have a reflection over the x - axis since the negative is outside paranthesis. Then a horizontal stretch be a factor of 5.
Also a vertical shift by a factor of 3.
So this means everytime you find a point for then you reflect it over the x - axis with a horizontal stretch w/a factor of 5 and move it up 3 units vertically.
Now for the next:
This one is much tougher. Read through this and try:
