Hi, here is the solution,

f(x)= x^2 e^17x.

(i) Horizontal asymptote:

There are no asymptotes, because the curve is a simple polynomial.

Note: For simple polynomial asymptotes does not exist.

Critical point:

To find the critical point, we have to find the derivative and equate to zero, then find the values for x.

f(x) = x^2. e^17x

f '(x) = 2x. e^17x +17 x^2. e^17x

f'(x) = xe^17x( 2+ 17x)

Now, make f '(x)=0

so, x e^17x (2+17x) =0

2+17x = 0

17x = ...
