Does the graph of the function y–x^2=9 intersect with the following axes? if the answer is ‘yes’, determine the coordinates of the points of intersection with the specified axis.

the 'y' axis

the point of intersection is:

The random variable x has probability density function f (x) = k(−x²+5x−4) 1 ≤ x ≤ 4 or =0 1 show that k = 2/9 find 2 e(x), 3 the mode of x, 4 the cumulative distribution function f(x) for all x. 5 evaluate p(x ≤ 2.5). 6 deduce the value of the median and comment on the shape of the distribution.
