A function $f:\mathbb{R^2} \rightarrow \mathbb{R}$ is called degenerate on $x_i$, if $f(x_1,x_2)$ remains constant when $x_i$ varies $(i=1,2)$. Define $f(x_1,x_2) = \mid 2^{\pi _i/x_1} \mid ^{x_2} \text{ for } x_1 \neq 0$, where $i = \sqrt {1}$. ... $x_1$ but not on $x_2$ $f$ is degenerate on $x_2$ but not on $x_1$ $f$ is neither degenerate on $x_1$ nor on $x_2$

Given a positive integer $m$, we define $f(m)$ as the highest power of $2$ that divides $m$. If $n$ is a prime number greater than $3$, then $f(n^31) = f(n1)$ $f(n^31) = f(n1) +1$ $f(n^31) = 2f(n1)$ None of the above is necessarily true

Admission Query GATE 2019
For ~77 marks (GO Estimated AIR 5355, Score ~882) in GATE 2019, is there a chance of getting direct admission into IISc or IIT Bombay/Delhi? The rank has been dropping steadily in the last few days. I'm very confused as I would like to ... admissions seem improbable. GO has taken me this far but I'll need a little more help :D Any insights would be really appreciated!
