First, we must find g(f(x)), which means we need to plug in f(x) into the expression for g(x):
g(f(x)) = (f(x) + 5) / (f(x))
= [(x^2 + 5) + 5] / (x^2 + 5)
= (x^2 + 10) / (x^2 + 5)
Now, we can find (g°f)(-3) by plugging in -3 for x in g(f(x)):
(g°f)(-3) = (f(-3) + 5) / f(-3)
= [( (-3)^2 + 5 ) + 5] / ( (-3)^2 + 5 )
= (9 + 5) / (14)
= 7/2
Therefore, (g°f)(-3) = 7/2.
Let f(x)=x^2+5 and g(x)=x+5/x. Find (g°f)(-3)
