Question

Confused can someone help pls

Answer 1

For this case, we have that by definition, be given two functions f (x) and g (x). So:

$(f-g) (x) = f (x) -g (x)$

We have:$f (x) = - 3x-5\\g (x) = 4x-2$

So:

(f-g) (x) = - 3x-5- (4x-2)

We have to:

$- * + = -\\(f-g) (x) = - 3x-5-4x + 2$

Equal signs are added and the same sign is placed while different signs are subtracted and the sign of the greater is placed

$(f-g) (x) = - 7x-3$
