Answer:

Step-by-step explanation:
Given
+ x
Multiply x by
to create a common denominator
=
+ x × 
=
+ 
= 
1.
Domain: {-1, 0, 2, 3}
Range: {2, 4, 6}
2.
Ax+By=C: linear equation standard form
y=mx+b: slope intercept form
(y-y^1)=m(x-x^1): point slope form
The answer in scientific notation is: 4.32 x 10^-2
