For the function g defined by g (x) = 70-3x find g (-x),-g (x), and - g (-x).

g (-x) = 70 + 3x - g (x) = - 70 + 3x - g (-x) = - 70 - 3x

Step-by-step explanation:

Put the minus signs where the problem statement tells you. As with any function, the argument replaces the variable in the function definition. That is, for g (-x), you put (-x) where x is in the definition of the function.

g (-x) = 70 - 3 (-x) = 70 + 3x

-g (x) = - (70 - 3x) = - 70 + 3x

-g (-x) = - (70 - 3 (-x)) = - 70 - 3x
