If f(x) = 4x + 7, g(x) = 3x2, find (f + g)(x).

Solution:

Given functions are f(x) = 4x + 7, g(x) = 3x2

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

= 4x + 7 + 3x2

= 3x2 + 4x + 7

Therefore, (f + g)(x) = 3x2 + 4x + 7

If f(x) = 4x + 7, g(x) = 3x2, find (f + g)(x).

Summary:

If f(x) = 4x + 7, g(x) = 3x2, then (f + g)(x) = 3x2 + 4x + 7
