0 if x <2

0.7 if 2 <= x < 2.5

F(x) = 0.8 if 2.5 <= x < 3

1 if x => 3

from first sight i think that this is a cumulative function

but then I saw that

P(x) > 1 if negative infinity < x < infinity.

i dont no if that matters though maybe i have the concept

of cumulative distribution completly wrong lol

thanks for any help

actually figured it out the function is not continous, so is not a distribution for a continuous random variable.

It is a distribution for a discrete random variable, but i dont know what the probability function would be;

0.7 if 2 <= x < 2.5

F(x) = 0.8 if 2.5 <= x < 3

1 if x => 3
