Question

If f(x)=4 and g(x)=7-x. Then (f+g)(x)=____ *​

Answer 1

Answer:

If f(x) = 4 and g(x) = 7-x, then (f+g)(x) = 11 - x

Step-by-step explanation:

The question is to find, (f+g)(x)

It is given that f(x) = 4 and g(x) = 7 -x

Then according to the algebra of real functions, this is the addition of two real functions. Suppose if we have an individual function 'f' and another individual function 'g', then the addition of these two functions can be written as,

     

               (f+g)(x) = f(x) + g(x)

By substituting the values,

           (f+g)(x) = 4 + 7 - x

                     = 11 - x

Hence the value of '(f+g)(x)' is '11- x'.
