Step-by-step explanation:
we are given

we will verify each options
option-A:
we can see that exponent is over 3
and it is positive and greater than 1
so, this function is increasing
so, this is FALSE
option-C:
At x=1:


At x=2:





So, it is getting tripled
so, this is TRUE
option-b:
we can plug x=0


so, this is FALSE
option-d:

Answer: 15
Step-by-step explanation:
=(−5−4)2+(−4−8)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√
d=(−5−4)2+(−4−8)2
=(−9)2+(−12)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾√
d=(−9)2+(−12)2
=81+144‾‾‾‾‾‾‾‾‾√
d=81+144
=2‾√25
d=225
=15
