f-¹(x)=
Answer:
Solution given:
f(x)=
Let f(x)=y
y=
Interchanging role of x and y
x=
doing crisscrossed multiplication
x(y+7)=-2y+2
now solve it:
xy+7x=-2y+2
keep like terms in one side
xy+2y=2-7x
take common
y(x+2)=2-7x
make a value of y
y=
So,
f-¹(x)=
Answer:
w= -2
Step-by-step explanation:
3w + 2 = 8 + 6w
Subtract 3w from each side
3w-3w + 2 = 8 + 6w-3w
2 = 8+3w
Subtract 8 from each side
2-8 = 8-8+3w
-6 = 3w
Divide each side by 3
-6/3 = 3w/3
-2 =w
