solve the inequality algebraically
11x3 is greater than or equal to  4x^2

college algebra  Reiny, Friday, November 23, 2012 at 6:45pm
11x  3 ≥ 4x^2
4x^2 + 11x  3 > 0
(x+3)(4x1) ≥ 0
critical values are x = 3 and x = 1/4
and y = 4x^2 + 11x  3 is a parabola opening upwards, with intercepts 3 and 1/4 .....
so x ≤  3 OR x ≥ 1/4
