WHAT IS IT CAN YOU TELL PLEASE

What’s 8y+48 and factor each expression completely

Which exponential function has an initial value of 2? f(x) = 2(3x) f(x) = 3(2x)

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.
