[tex] \boxed{B. 5 {x}^{3} + 2x - 1} [/tex]

Given:

[tex]f(x) = 5{x}^{3} - 2 \\ \\ g(x) = 2x + 1[/tex]

To Find:

[tex](f + g)(x) = f(x) + g(x)[/tex]

Step-by-step explanation:

[tex] = > f(x) + g(x) = (5{x}^{3} - 2) + (2x + 1) \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 5{x}^{3} - 2 + 2x + 1\\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 5 {x}^{3} + 2x - 2 + 1\\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 5 {x}^{3} + 2x - 1[/tex]
