Question

PLease Help Me Its A math Problem !!! As what value of x does the function f(x)=2(3)x overtake the function g(x)=2x^2+4x?

Question options:

x = 2


x = 3


x = 4


x = 1

Answer 1

x=2

Explanation:

To test when the function f(x) over takes the function g(x)

I just plugged in the x values

X f(x) g(x)

1 6 6

2 12 16

3 18 30

4 24 48

We can see from this table that f(x) is greater than g(x) starting from x=2

Therefore I think x=2 is your answer.

Hope this helps! :)
