Question

Please Help, for each function interchange x and y then solve for y to determine the inverse. I know you have to switch but i can't do the exact algebra.
A) y=2-1/2x

Answer 1

subtract 2 from both sides and multiply by 2. assuming it's
\[y=2-\frac{ x }{ 2 }\]

Answer 2

multiply by -2 not 2

Answer 3

Okay but would it not be x-2=-1/2x. Now i don't know how to get rid of that -1/2x

Answer 4

is your function the line I showed?

Answer 5

or this
\[y=2-\frac{ 1 }{ 2x }\]

Answer 6

Answer 7

is the x in the denominator or not

Answer 8

no it is not

Answer 9

its outside the fraction
