Evaluate the functions for the values of x given as 1, 2, 4, 8, and 16. Describe the differences in the rate at which each function changes with increasing values of x.
--------------
f(x) = 2x^3 + 7x^2 -x-1
---
f(1) = 2 + 7 - 1 - 1 = 7 ; plot point (1,7)
----
f(2) = 2(2^3) + 7*2^2 -2 - 1
= 2*8 + 7*4 -3 = 16 + 28 - 3 = 41 ; plot point (2,41)
---
f(4) = 2(4^3) +7*4^2 - 4 - 1
= 2*64 + 7*16 - 5 = 235 ; plot point (4,235)
----
f(8) = 2(8^3) + 7(8^2) -8 - 1 = 1463 ; plot point (8,1463)
------
f(16) = 9967 ; plot point (16,9967)
------------------------------------
The function is increasing at a pregressively faster and faster pace
as x increases from one to 16.
