Question 824344
For the given functions f and g, find the requested function and state its domain.
f(x) = 3x + 5; g(x) = 7x + 8
Find f · g. 


f * g = f(x)*g(x)


f * g = (3x+5)*(7x+8)


f * g = 3x(7x+8)+5(7x+8)


f * g = 21x^2+24x+35x+40


f * g = 21x^2+59x+40


Domain of f * g is the set of all real numbers.
