Question

Use a table of function values to approximate an x-value in which the exponential function exceeds the polynomial function.

f(x) = 3(3)^(2x-5)
h(x) = (x + 1)5 + 4

x = 5
x = 6
x = 7
x = 8

Answer 1

what they said

Explanation:

Answer 2

x = 7

Explanation:

It is convenient to let a graphing calculator or spreadsheet create the table. (see attached) We find that f(7) > h(7), while f(6) < h(6). The appropriate choice seems to be ...

x = 7.
