Given the function: How can you restrict the domain so that f(x) has an
inverse? What is the equation of the inverse function?
f(x) = x² – 2x
O x2 0; f-1(x) = 1+Vx+1
O x 21; p-1 (x) = 1 +Vx+1
O x > 0; p-1(x) = 1-7X+1
O x 21; p-1(x) = 1-Vx+1

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

i believe the answer is the polygon, heptagon.
