any help with this question would be greatly appreciated!

(1 point) a. Assuming a, b and k are constants, calculate the following derivative. at " ek ) = b. Find a value of k so that ek is a solution to x = k = [3 8 ] C. Find a value of k so that " is a solution to * = k = d. Write down the general solution in the form X1(t) =? and X2(t) =?, i.e., write down a formula for each component of the solution. Use A and B to denote arbitrary constants. x1 (1) = X2(1) =
