Guest: How do I get the denominator to equal zero for the problem 2x^2-3x over 4x^2+1?
You want to know when 4x
2 + 1 = 0 so that you can determine the asymtotes? Is that correct?
Think about this
x
2 >= 0 (because any number squared can never be negative)
therefore,
4x
2 >= 0
therefore
4x
2 +1 >= 1
Hence the denominator cannot be zero.
This is what the graph looks like.
