Answer:

42.9%

Step-by-step explanation:

So you would use [ ((V2 - V1) / |V1|) * 100 ]

V1 = 87.5 to V2 = 125

= ((125 - 87.5) / |87.5|) * 100

= (37.5 / 87.5) * 100

= 0.428571 * 100

= 42.8571% change

= 42.8571% increase

Then you round to 42.9!

Hope it helps! :)

f(x)=3x
g(x)=9x^3-4

g(f(x))=9(3x)^3-4=243x^3-4
f(g(x))=3(9x^3-4)=27x^3-12
we can see that g(f(x)) with yield a higher value for x=10
