Homework Help: Wave function

what would a wave function of

phi(x) = Ke^(-a|x|)

look like?

would it be like an exponential graph with a graph reflected along the y axis?

and its probability distrubution (phi)^2?
i have no idea...i can't seem to find it by googling.

Yes. Try plotting a few values

$$|\Psi (x)|^2$$ is the probability density.

The probability of measuring a position in the interval [a, b] is the integral of $$|\Psi (x)|^2$$ evaluted between a and b, make sure to normalise the wavefunction first.
nb: This is 1-particle in 1-dimension, which is what I suspect you want.
