# Math Help - Upeer and Lower bouds of big O
1. ## Upeer and Lower bouds of big O
Is my working of this problem ok?
f:N->R
f(n) = $\frac{n^2+2log2n}{n+1}
$
prove f(n) = O(n) < - - - thats big O with a "-" in it
$|f(n) | = |\frac{n^2+2log2n}{n+1}|$
= $\frac{n^2+2+log2n}{n+1}$ since each term is >=0
<= $\frac{n^2+... | {} |
# Using Keras to Predict a Function Following a Normal Distribution
