We are given with the equation
y = e^-9x with the restriction of x <span>≥ 0
If rotated about the x-axis the area of the resulting surface is
A = </span>π ∫ y² dx
Substituing
A = π ∫ (e^-9x)² dx
A = π ∫ e^-18x dx
The limits are from 0 to positive infinity.

Step-by-step explanation:
<u>Exponent Rule:</u>
When dividing exponents, they're subtracted.
Since the second term has a negative exponent, we add.
<u>Change the problem into multiplication, then add 4 to the exponent of -6:</u>
