Please help me if you are good at math!

Answers:
y = 5(0.05) = 95% rate of decay
f(t) = 95(1.05) = 5% rate of growth
g(t) = 95(0.95) = 5% rate of decay
y = 5(1.95) = 95% rate of growth

Explanations:
y=5(0.05) has a 95% rate of decay because the number 5 is going down by 95%

f(t) = 95(1.05) has a 5% rate of growth because the number 95 is going up by 5%

g(t) = 95(0.95) has a 5% rate of decay because the number 95 is going down by 5%

y = 5(1.95) has a 95% rate of growth because the number 5 is going up by 95%

Hope this helped!
