If a is an integer and `a in (-5,30]` then the probability that the graph of the function `y=x^(2)+2(a+4)x-5a+64` is strictly above the x-axis is

If a is an integer lying in [-5,30], then the probability that the probability the graph of y=x^(2)+2(a+4)x-5a+64 is strictly above the x-axis is 1/6 b.7/36 c.2/9 d.3/5

The probability that the graph of y=16x^(2)+8(a+5)x-7a-5=0, is strictly above the x-axis,If a in[-20,0]

The graph of the function y=16x^(2)+8(a+5)x-7a-5 is strictly above the x axis,then 'a' must satisfy the inequality

If a in[-6,12], the probability that graph of y=-x^(2)+2(a+4)x-(3a+40) is strictly below x axis is

Draw the graph of following function y=4x^(3)-30x^(2)+72x-55
