Question

Given j(k) = 4/3K2 – 7k + 1, find the value of J(-12).

Answer 1

Step-by-step explanation:

To find the value of j, we must plug the value given by the exercise for j into both equations;

So the exercise is as follows:

`\begin{gathered} j=(4)/(3k^2)-7k+1 \\ j=(4)/(3(-12))-7(-12)+1 \\ j=(4)/(-36)-7(-12)+1 \\ j=(4)/(-36)+84+1 \\ j=(4)/(-36)+85 \\ j=(340)/(-36) \\ j=-9.4 \\ \text{the answer is -9.4} \end{gathered}`
