The domain for f(x) and g(x) is the set of all real numbers. let f(x) = 2x-3 and g(x) = 3x +8 find f(x)g(x). show work

The value of f(x)g(x) is  

Solution:

The domain for f(x) and g(x) is the set of all real numbers

From question give that

f(x) = 2x – 3   -----     (1)

g(x) = 3x + 8  -------      (2)

We need to evaluate f(x)g(x), so we need to multiply eqn 1 and eqn 2

f(x)g(x) = (2x – 3)( 3x + 8)              [Using equation (1) and (2)]

Open the bracket and multiply the terms in above equation,

Hence the value of f(x)g(x) is  

its 4 because 2 times 2 is 4, if you double the number two you get four
