# If f(x) = 4x + 7, g(x) = 3x^{2}, find (f + g)(x).

**Solution:**

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

We know the property of addition of functions that (f + g)(x) = f(x) + g(x)

= 4x + 7 + 3x^{2}

= 3x^{2 }+ 4x + 7

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

## If f(x) = 4x + 7, g(x) = 3x^{2}, find (f + g)(x).

**Summary:**

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