X^2 + 30x + 21
= ( x + 15)^2 - 225 + 21
= (x + 15)^2 - 204
Its D minimum at -204
Kind of the whole point of an infinite geometric series is that you can't find the sum. If it is infinite, then the sum is infinite.
The graph looks like this, on the enclosed pic:
One feature is that it's periodic and torn (has cut-off points), meaning the domain is the same as in case of tan(x): x€R and x =/= π/2+πn.
The range equals the range of arcsin(x): -π/2<=y<=π/2 OR y€[-π/2;π/2]
Hope could understand and if it helped! :)
