(Very easy, I'm not in the mood for math though) Giving brainliest for correct answer only. Answer ASAP this is timed!

Let f(x) = 3 − x . find the average rate of change of f(x) from x = a to x = a + h and simplify your answer so that no single factor of h is left in the denominator.

For f(x) = 3x+1 and g(x) = x2 - 6, find (g/f)(x)

Find the directions in which the function increases and decreases most rapidly at upper p 0p0. then find the derivatives of the function in these directions. f(x, y)equals=x squared plus xy plus y squaredx2+xy+y2, upper p 0p0left parenthesis 1 comma negative 4 right parenthesis
