Solving Continuous Functions: Find g(3) When f(3)=5 and lim x→3 [2f(x)-g(x)]=4

Click For Summary
SUMMARY

The problem involves finding the value of g(3) given that f(3) = 5 and the limit as x approaches 3 of the expression [2f(x) - g(x)] equals 4. By applying the properties of limits and the continuity of functions, it is established that lim x→3 g(x) = g(3). Therefore, substituting the known value of f(3) into the limit equation leads to the conclusion that g(3) must equal 6.

Homework Statement


If f and g are continuous functions, with f(3) = 5 and \stackrel{lim}{x\rightarrow3}\left[2f(x) - g(x)\right] = 4 find g(3)


The Attempt at a Solution


I'm stumped! I cannot find anything in my notes on where to begin. I am not looking for a specific answer, I just need to be pointed in the right direction. Where do I begin?

try taking the limit, you know the limt of f
 
And you know, by the continuity of g, that
\lim_{x \rightarrow 3} g(x) = g(3)
