Given functions f(x) and g(x): f (x) = x + 2

g(x) = x + 1/2

...what is the coefficient of the x term of f(x) · g(x)?
Find the coefficient for the x term of the answer to (fºg)(x). Write the answer as a fraction
(enter fractions write as a slash i. e. 1/2 for ) or as
a decimal. Do not include spaces in your response.
