That minimum value is. y (2) = 2 3 â 3 Â· 2 2 + 2 = 8 â 12 + 2 = â2. b) y = â2 x 3 â 3 x 2 + 12 x + 10. At x = 1 there is a maximum of y = 17. At x = â2 there is a minimum of y = â10. c) y = 2 x 3 + 3 x 2 + 12 x â 4. Since f ' (x) = 0 has no real solutions, there are no extreme values. d) y = 3 x 4 â 4 x 3 â 12 x 2 + 2.
Indirectly, physics has contributed to forensic science via the invention of the microscope, the electron microscope, the mass spectrometer, and optical spectrometers; but directly, its role in forensic science has been minimal.
Forensic scientists use the science of chemistry to help them find DNA and blood samples and fingerprints from crime scenes to help them find clues to solve the crime. There'sâ¦ a substance called cobalt-thiocyanate reagent that's used as a field test for cocaine. It turns blue if there is the presence of cocaine.
