Apply the quotient rule, which is:
dxdg(x)f(x)=g2(x)−f(x)dxdg(x)+g(x)dxdf(x)
f(x)=x−3 and g(x)=x−2.
To find dxdf(x):
-
Differentiate x−3 term by term:
-
The derivative of the constant −3 is zero.
-
Apply the power rule: x goes to 1
The result is: 1
To find dxdg(x):
-
Differentiate x−2 term by term:
-
The derivative of the constant −2 is zero.
-
Apply the power rule: x goes to 1
The result is: 1
Now plug in to the quotient rule:
(x−2)21
