Find an equation of the plane that contains point $P=(-2,3,5)$ and is perpendicular to the vector vec$(n)=($:$3,-4,2$:$).$ Your answer should actually be a

Python's lambda expression called $z,$ which is of the form

$z=$ lambda $x,y$:$a**x+b**y+c$

where you just need to find the appropriate values of $a,b$ and $c.$ For example, if you think the solution is the plane $z=5x-\frac{4}{5}y-1,$ in the answer

cell you should write

$z=$ lambda $x,y$:$5**x-\frac{4}{5}**y-1$

The key word lambda creates a so called lambda expression $($a$.$k$.$a$.$ anonymous function$),$ which is a function with input variables $x$ and $y.$
