Answer 1

I got -x/2+1/2. I'll get back to you in a lil bit.

Answer 2

Y = 1 - 2x

-1

y-1 = - 2x

÷ -2

y-1/-2 = x

f-1(x) = x - 1/-2

Let's make x = 7

7-1/-2 = - 3

Or

y = 1 - 2x

+2x

y + 2x = 1

-y

2x = 1-x

÷2

x. = 1-x/2

f-1(x) = 1 - x/2 is your answer

Let's make x=7

1-7/2 = - 3

Hope this helps!
