Given that f(x)=-x^2+12x-28 has a relative maximum at x=6 choose the correct statement. A. f' is negative on the interval (-infinity,6)
B. f' is positive on the interval (-infinity, infinity)
C. f' is negative on the interval (6, infinity)
D. f' is positive on the interval (6,infinity)
E. none of these

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
