Thinking about the areas of a Standard Normal Distribution, as z values decrease, do the areas to the left of z increase, or dec
rease?
1 answer:
The figure below shows the standard normal distribution or "bell-shaped" curve, plotted against the z-score.
The z-score is defined as
z = (x - μ)/σ
where
x = nrandom variable
μ = mean
σ = standard deviation.
As z-values decrease, areas to the left of z decrease as shown by the shaded area.

Step-by-step explanation:
Auxialary equation is
General solution is
Eliminate B to get
3A =a-1
We know that y tends to 0 when x tends to infinity for any finite A
i.e. a should be a finite real number.
