Find the derivative of the function using the definition of derivative. g(x) = 9 - x
Solution:
It is given that
g(x) = 9 - x
The derivative of the given function is
\(\\g'(x)=\lim_{h\rightarrow 0}\frac{f(x+h)-f(x)}{h} \\ \\Substituting\: the \: values \\ \\g'(x)=\lim_{h\rightarrow 0}\frac{[5-(x+h)]-[5-x]}{h} \\ \\g'(x)=\lim_{h\rightarrow 0}\frac{5-x-h-5+x}{h} \\ \\By\: further\: calculation\)
\(\\g'(x)=\lim_{h\rightarrow 0}\frac{-h}{h} \\ \\g'(x)=\lim_{h\rightarrow 0}-1\)
g’(x) = -1
Therefore, the derivative of the function is -1.
