Answer:
Any value of x x makes the equation true. All real numbers Interval Notation: ( − ∞ , ∞ ) .
Yes it is.
See below.
Step-by-step explanation:
(2x^2-18)(x+3)(x-3)
= (2x^2 - 18(x^2 - 9)
= 2x^4 - 18x^2 - 18x^2 + 162
= 2x^4 - 36x^2 + 162.
The left side transforms to the right side so it is an identity.
The angles and lengths should not change at all the image and pre-image should be the same just at a different place on the graph
