what is the percent rate of change in function y= (0.98)^x determine whether the function represents exponential growth of exponential decay
2% growth
20% growth
2% decay
0.2% decay
5logb(y) + 4logb(x)
logb(y^5+x^4)
logb(y^5x^4
(5+4) logb(y+x)
logb(yx^5+4)
3e^2x + 2 = 28
1.0797
0.4689
0.9261
2.1595
I really need help with these three problems.
Thank you in advance!

2% decay
all you do here is compute the function when x is equal to 1 (which gives 0.98), when x is equal to 2 (which gives 0.9604) and compute the percentage difference which is:
((0.98  0.9604) / 0.98) X 100
Or more generally:
((initial value  changed value) / initial value) X 100
logb(y^5+x^4)
You can't answer the third one without knowing the value of x.
