Number of terms is 3
Degree is 2 ( from $y^2$ )

Explanation:

Instead of being a function in $x$ this is a function in $y$

That is: not $f(x)$ but $f(y)$

Grouping terms we have:

$(y^2-3y^2)+(2y-5y)+5$

$-2y^2-3y+5$

Number of terms is 3
Degree is 2 ( from $y^2$ )
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In fact this is a quadratic in $y$ and behaves in the same way as a quadratic in $x$ but it is rotated by $90^0$

As we have $-2y^2$ the general shape is $sup$
