Question

Add: f(x)+g(x) f(x) = 2x2 – 3x² + 7x+1 g(x) = 4x2 + 5x +12 Submit

Answer 1

Answer:

$f(x) + g(x) = 2x^3 + x^2 + 12x + 13$

Step-by-step explanation:

We are given these following functions:

$f(x) = 2x^3 - 3x^2 + 7x + 1$

$g(x) = 4x^2 + 5x + 12$

Add: f(x)+g(x)

To add them, we combine the like terms. So

$f(x) + g(x) = 2x^3 - 3x^2 + 7x + 1 + 4x^2 + 5x + 12 = 2x^3 + (-3+4)x^2 + (7+5)x + 1 + 12 = 2x^3 + x^2 + 12x + 13$

The added function is:

$f(x) + g(x) = 2x^3 + x^2 + 12x + 13$
