Answer:
(f-g) (144) = 0.
Step-by-step explanation:
Given : f(x) = [tex]\sqrt{x}+12[/tex] and g(x) = [tex]2\sqrt{x}[/tex] .
To find : what is the value of (f – g)(144).
Solution : We have given
By the formula : (f – g)(x) = f(x) - g(x)
(f – g)(144) = f(144) - g(144).
f(x) - g(x) = [tex]\sqrt{x} +12 -2\sqrt{x}[/tex].
(f-g) (x) = 12 - [tex]\sqrt{x}[/tex].
(f-g) (144) = 12 - [tex]\sqrt{144}[/tex].
(f-g) (144) = 12 -12
(f-g) (144) = 0.
Therefore, (f-g) (144) = 0.
