please mark me as brainlest
Not sure if that's a multiplication or a composition. It doesn't matter. Both f and g have a domain of all real numbers. The domain of
![( f \circ g)(x)=f(g(x))](https://tex.z-dn.net/?f=%28%20f%20%5Ccirc%20g%29%28x%29%3Df%28g%28x%29%29)
is the same as the domain of g(x), all real numbers
Answer: all real numbers
Equation :
[x(x+4)]/2=6 (as (b*h)/2=A)
x*x + 4*x -12 = 0
so, x = 2 units(as -6 is negative)
