# Perform the requested operation or operations. f(x) = 4x + 7, g(x) = 3x^{2}. Find (f + g)(x)?

**Solution:**

Given f(x) = 4x + 7, g(x) = 3x^{2}

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 + 3x^{2}

Thus, the operation (f + g)(x) is performed and the result is (f + g)(x) = 3x^{2}+ 4x + 7

## Perform the requested operation or operations. f(x) = 4x + 7, g(x) = 3x^{2}. Find (f + g)(x)?

**Summary:**

If f(x) = 4x + 7, g(x) = 3x^{2}, the operation is performed and (f + g)(x) = 3x^{2}+ 4x + 7
