Arrange the functions in descending order, starting with the function that eventually has the greatest value and ending with the function that eventually has the least value.

4x+9

9^x+1

x^2+3

4x

9^x

x^2

I'll just assign a value of x and solve it so that I'll be able to arrange them in order from greatest to least.

I am assuming that x = 2.

4x + 9 ⇒ 4 (2) + 9 = 8 + 9 = 17

9^x + 1 ⇒ 9² + 1 = 81 + 1 = 82

x² + 3 ⇒ 2² + 3 = 4 + 3 = 7

4x ⇒ 4 (2) = 8

9^x ⇒ 9² = 81

x² ⇒ 2² = 4

based on my assumption, the order from greatest value to least value is:

1) 9^x + 1

2) 9^x

3) 4x + 9

4) 4x

5) x² + 3

6) x²
