Comparing four Functions

x-values A (linear) B (quadratic) C (quartic) D (exponential)
1 50 10 1 1.25
10 500 1000 10,000 9.313
20 1000 4000 160,000 86.736
30 1500 9000 810,000 807.794
40 2000 16000 2,560,000 7523.16

The table shows values four functions evaluated at the same x-values. Which function will have the largest value as x → ∞?

{The functions are labeled A, B, C, and D in the columns.]
