Identify the kernel and normalizing constant for the following probability density functions:
The Exponential Distribution: f[z; A] = Ae^(-Az)
The Gamma Distribution: f[z;a, 8] = (1/Γ(a)) * (1/β)^a * z^(a-1) * e^(-z/β)
The Normal Distribution: f[z; μ,σ] = (1/√(2πσ^2)) * e^(-(z-μ)^2/(2σ^2))
The Laplace Distribution: f[z;μ,b] = (1/2b) * e^(-|z-μ|/b)
The Beta Distribution: f[z;a,b] = (1/B(a,b)) * z^(a-1) * (1-z)^(b-1)
The X^2 Distribution: f[z;n] = (1/(2^(n/2) * Γ(n/2))) * z^(n/2-1) * e^(-z/2)
The Student-t Distribution: f[x;n] = (1/(√(nπ) * B(1/2, n/2))) * (1 + (x^2/n))^(-(n+1)/2)
