If I get a question that gives me a function defined in variables and then certain F(X) and F'(X) with numbers that equal the slopes, and I need to find the derivative of the first function do I just substitute in.(adsbygoogle = window.adsbygoogle || []).push({});

For example:

Find the value of F'(8) when

[tex]f(x)/f(x)-g(x)[/tex]

while [tex]f(8)= 3, f'(8) = 2 , g(8) = 4 , g'(8) = 3 [/tex]

do I just do:

[tex]F(X) = 3 / 3-4[/tex] and then use Newtonian qoutient to got the derivative of F(X) at 8 ?
