f x 4xx3 and g x x3 therefore fg3Solutionfx 4x x3 gx x 3

f (x)= 4x-x^3 and g (x)= x+3 therefore, (f/g)(-3)=

Solution

f(x) = 4x - x³

g(x) = x +3

==> (f / g)(x) = f(x) / g(x)

==> (f / g)(x) = (4x - x³) / (x +3)

==> (f / g)(-3) = (4(-3) - (-3)³) / (-3 +3)

==> (f / g)(-3) = 15 / 0 = undefined

Hence (f / g)(-3) = undefined.
