Use a table of function values to approximate an x-value in which the exponential function exceeds the polynomial function. f(x) = 3(4)(2x-4). h(x) = (x + 2)3 + 1.
D) x= 4
D) x= 4
Answer:
The correct option is D.
Step-by-step explanation:
The exponential function is
[tex]f(x)=3(4)^{2x-4}[/tex]
The polynomial function is
[tex]h(x)=(x+2)^3+1[/tex]
Find the values of both functions at x=-3, 0, 2, 4.
x values f(x) h(x)
-3 0.0000029 0
0 0.012 9
2 3 65
4 768 217
From this table we can say that the exponential function f(x) exceeds the polynomial function g(x) at x=4.
Therefore the correct option is D.
