Answer 1

all have a domain of (-inf, inf)

so its a case of sorting out the range

well if you think about.... 3 to the power 2 is 9 3 to the power 4 is 81 so as the power gets larger the value of 3^x gets larger...

where as 0.25^x or \[(\frac{1}{4})^x = \frac{1^x}{4^x}\]

so in this case as x gets larger the value of (0.25)^x gets closer to zero

if x = 1 you have 0.25 if x = 3 you have 1/64

so which of the last 2 choices gets close of 4 as x gets very large...
