Question

Let f(x)=5x^3-2x and g(x)=3x^3 . Perform the indicated operation and state the domain. f(x)+g(x)

Answer 1

f(x)+g(x) = \(( 5x^3-2x)\) + \((3x^3)\)

Answer 2

the options are A. 8x^3-2x; all real numbers
B. 2x^3-2x; all real numbers
C. 8x^3+ 2x; all real numbers
D. 2x^3+2x' all real numbers

Answer 3

so... solve it, simplify it, and then we'll check the domain :)

Answer 4

got it , thanks 8x^3-2x
