Find the area bounded by the curve `x=7 -6y-y^2`.

Answer

A

Explanation

Given function is
`y=e^(-x)
When x=0
y=e^(-0)=1
` x increases value of y decreases and only at x=oo
y=0

So, the required area can be founded out by integrating the functon from `0 to oo. Area =int^oo_0 e^(-x) dx
= - [e-e^(-x)0_0
=-[0-1]=1`
