Ответ:
2x² -4x -4
Step-by-step explanation:
(f-g)(x) = f(x) - g(x) = (2x² -3x) -(x +4)
= 2x² -3x -x -4
= 2x² -4x -4
Ответ:
M=3
Now you need b, so plug the x-coordinate and y-coordinate into the x and y in the equation to find the b.
-5=3(-3)+b
-5=-9+b
Add 9 to both sides to isolate the b
-5=-9+b
+9. +9
4=b
So the equation is
Y=3x+4
