Answer:
(g-f)(3) = 20
Step-by-step explanation:
g(3)=6 * (3) = 18
f(3)= 4-2(3) = 4 - 6 = -2
So
(g-f)(3) = 18 - (-2) = 20
-18x
you first times the numbers, which becomes -18
Next you add the exponent from the veriables (x) (if you're diving you're subtractiong example: x^a/x^b = x^a-b)
Sooo when you add them you get 8-7=1 which means.. x^1 (but you don't need to put the 1)
-18x
Step-by-step explanation: You can't continue on with the problem until the denominators are the same. So you need to find the LCD (Least Common Denominator). For example...
The LCD is six
