Question

Given the functions f(x) = x4 and g(x) = 4.2 x squared, which of the following

statements is true?
Submit Answer
f(3) = g(3)
f(3) < g(3) or f(3) > g(3)​

Answer 1

f(3) > g(3)​

Explanation:

Assuming
`f(x)=x^4` and
`g(x)=4\cdot2^x`

Then
`f(3)=3^4=81` and
`g(3)=4\cdot2^3=4*8=32`

Since 81>32, it follows that f(3)>g(3)

Hence the true statement is f(3) > g(3)​

The last choice is correct
