Question

For the function k(x)=-1/16x-8 what is the inverse function of k^-1(x)?

Answer 1

k^-1(x) = -1/128+16x

Domain = ]-infinity,-8[ U ]-8,infinity[

Range = ]-infinity,0[ U ]0,infinity[

Explanation:

k(x) = -1/16x = -8

y = -1/16x = -8

x = -1/16y = -8

y = -1/128+16x

k^-1(x) = -1/128+16x

Answer 2
