TRUE OR FALSE AND WHY If f35 and g510 then fg310Solutionf3

TRUE OR FALSE AND WHY

If f(3)=5 and g(5)=10 then (fg)(3)=10.

Solution

f(3) = 5

g(5) = 10

(fog)(3) :

f(g(3))

We arent given g(3) value here

So, this is FALSE

------------------------------------------------------

P.S :
If we had to fund gof(3 on the other hand :

g(f(3)) :

g(5)

which is indeed 10
