Find a and k and then evaluate the function. Round your answer to three decimal places when necessary.f(x) = 
with f(0) = 1 and f(1) = 0.5. Find f(2).
A. a = -2, k = ln(2.25), f(2) = 0.141 B. a = 2, k = ln(1.75), f(2) = 0.377 C. a = -2, k = ln(1.75), f(2) = 0.377 D. a = 2, k = ln(2.25), f(2) = 0.235
Let S be the set of all even integers, and define a function f: Z ?? S as follows:
Find the absolute maximum and absolute minimum values of the function, if they exist, over the indicated interval, and indicate the x-values at which they occur.f(x) = x3 - x2 - x + 6; [0, 2]
A. Absolute maximum = 6 at x = 0; absolute minimum = 5 at x = 1 B. Absolute maximum = 8 at x = 2; absolute minimum = 5 at x = 1 C. Absolute maximum = 8 at x = 2; absolute minimum = 6.2 at x = 0 D. Absolute maximum = 6.2 at x = 2; absolute minimum = 5 at x = 0
