Yall what is this monstrosity
(click on the picture, it was cropped a bit)

Step-by-step explanation:

f(x)=x^2+12

f(m)=m^2+12

3[f(m)]=3m^2+36(1)

f(3m)=9m^2+12(2)

It is Given that f(3m)=3[f(m)]

From (1) and(2)

3m^2+36=9m^2+12

m^2=4

m=2 or-2

But it's given that m>0

Thus m=2

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6
