Least to greatest 2^x, x^2-20, x^5-4x^2+1, x+30, x^4-1, x^3+x^2-4, -x^2+x

x^2-20, -x^2+x, 2^x, x^3+x^2-4, x^4-1,  x^5-4x^2+1,  x+30 (Least to greatest)

Step-by-step explanation:

Let x take any positive integer, x=2.

#Substitute x with 2 in all the functions to get determine the least to greatest:

Using our calculated values, we can arrange the functions from the least to greatest as:

x^2-20, -x^2+x, 2^x, x^3+x^2-4, x^4-1,  x^5-4x^2+1,  x+30
