Perform the requested operation or operations. f(x) = 4x + 7, g(x) = 3x2. Find (f + g)(x)?
Solution:
Given f(x) = 4x + 7, g(x) = 3x2
A function is defined as a relationship between one variable (the independent variable) and another variable (the dependent variable).
Let f and g be functions with domains A and B. Then the functions f + g is defined as,
(f + g)(x) = f(x) + g(x)
We just need to add the two functions
(f + g)(x) = 4x + 7 + 3x2
Thus, the operation (f + g)(x) is performed and the result is (f + g)(x) = 3x2+ 4x + 7
Perform the requested operation or operations. f(x) = 4x + 7, g(x) = 3x2. Find (f + g)(x)?
Summary:
If f(x) = 4x + 7, g(x) = 3x2, the operation is performed and (f + g)(x) = 3x2+ 4x + 7
