Given that k(x) is a one-to-one function and k−1(x) is the inverse of k(x) , if k−1(12)=1/15 and k^−1(15)=12 , explore the function numerically to determine k(12) .(1 point) Responses k(12)=15 k left parenthesis 12 right parenthesis equals 15 k(12)=1 k left parenthesis 12 right parenthesis equals 1 k(12)=115 k left parenthesis 12 right parenthesis equals Start Fraction 1 over 15 End Fraction k(12)=−15
To determine k(12), we need to use the information we have about the inverse function.
From k^−1(12) = 1/15, we know that k(1/15) = 12.
From k^−1(15) = 12, we know that k(12) = 15.
Therefore, k(12) = 15.
