Which type of function best models the data in each table? Write an equation to model the data.
Table:
x | y
0 | 5
1 | 2
2 | 0.8
3 | 0.32
4 | 0.128
Please help me with this I'm really bad at graphs and functions..I know its either quadratic or exponential because I graphed it but I'm not sure. Please help me with the equation too, thank you so much :))

notice that each y is 0.4 times the previous. So,
y = 5*0.4^x
y = 5*0.4^x
