Given f(x) = 3x^2 + 5 and g(x) = x -2

what is (fg)(x)?

a. 3x^3 - 10
b. 3x^2 - x + 7
c. -3x^2 + x - 7
d. 3x^3 - 6x^2 + 5x - 10

D.  (fg)(x) = 3x^3 - 6x^2 + 5x - 10

Step-by-step explanation:

f(x) = 3x^2 + 5 and g(x) = x -2

(fg)(x) = (3x^2 + 5)(x -2)

(fg)(x) = 3x^3 - 6x^2 + 5x - 10

step-by-step explanation:

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
