Question

find f-g given that: f(x)=x^3-3x+2√x-7, g(x)=-6x^3+10x-√x

Answer 1

put a minus sign between them
use parentheses

Answer 2

\[x^3-x+2\sqrt x-7-(-6x^3+10x-\sqrt x)\] is a start

Answer 3

then distribute the minus sign
\[x^3-3x+2\sqrt x-7+6x^3-10x+\sqrt x\] and finally combine like terms

Answer 4

is that the answer ? because I don't see that as one of the choices

Answer 5

7x^3-13x+3√x-7
