Answer 1

@Michele_Laino

Answer 2

I think the linear function, because the linear function is an infinity weaker than exponential function and weaker than power function

Answer 3

wait which one?

Answer 4

5x?

Answer 5

yes! In general I call linear function a function like this:
f(x)=a*x+b
and y=5*x is a linear function with b=0

Answer 6

we can exclude sin(x) and log(x), because:
\[\log(x)\le x, \forall x \ge 1\]
furthermore we have:
\[-1\le \sin x \le 1\]

Answer 7

so is it A or D?

Answer 8

sorry i have to do this really quick

Answer 9

please, evalute this limit below:
\[\lim _{x \rightarrow + \infty}\frac{ x ^{20} }{ 2^{x} }=...\]

Answer 10

x^20

Answer 11

no is 0, (you have to use the De L'Hopital rule).
So x^20 is an infinity weaker than 2^x, and then 2^x increase faster than other function

Answer 12

so the answe is 2^x

Answer 13

yes!

Answer 14

it is the same as before, whit 2^x and 20^x
in which f(x)=x^20, and g(x)=2^x
so?

Answer 15

is it B

Answer 16

no, sorry!

Answer 17

oh

Answer 18

its not D

Answer 19

yes! it is not D

Answer 20
