The very bottom all the way to the right
Answer:
f(x)=-4x+/4
let y=f(x)
y=-4x+4
interchange the role of x & y
x=-4y+4
x-4=-4y
(x-4)/-4=y
y=-(x-4)/4
f-¹(x)=-(x-4)/4
yeah you are right
Answer:
x = 1.4 (or 21/15)
Step-by-step explanation:
12x - 15 = 6 - 3x
+3x +3x
-----------------------
15x - 15 = 6
+15 +15
-----------------------
15x = 21
/15 /15
----------------------
x = 21/15 or
x = 1.4
