Given f(x) = 4x + 13 and g(x) = 10x − 2, solve for (f + g)(x) and select the correct answer below. (f + g)(x) = 14x + 15 (f + g)(x) = 14x + 11 (f + g)(x) = 6x + 11 (f + g)(x) = 6x + 15

    \[\huge\rm \color{reD}{f(x)}+\color{blue}{g(x)}\] f(x) =4x+13 g(x)=10x-2 so replace f(x) and g(x) for 4x+13 and 10x-2 \[\huge\rm \color{reD}{(4x-13)}+\color{blue}{(10x-2)}\] combine like terms

    k here is my work: 4x + -13 + 10x + -2 4x+ -13 + 10x + -2 = (4x + 10x) + ( -13 + -2) = 14x + -15 Answer is : 14x -15
