Answer:
The first derivative of the given function

Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given f(x) = ae⁻ᵇˣ ...( i )
we will use differentiation formula

<em><u>Step(ii)</u></em>
Differentiating equation (i) with respective to 'x', we get

= -ab e⁻ᵇˣ

<u><em>Final answer:-</em></u>
The first derivative of the given function

9x^4 -225y^8
= 9(x^4 - 25y^8)
= 9(x^2 + 5y^4)(x^2 - 5y^4)

Answer:
y = -3
Step-by-step explanation:
The given line is a horizontal line thru -5 on the y-axis.
Your line is parallel to y = -5, hence is also a horizontal line and passes thru (2, -3). Since -3 is the y-coordinate of that point, y = -3 is the equation of the line you are looking for.
