What is the percent rate of change in function y

what is the percent rate of change in function y= (0.98)^x determine whether the function represents exponential growth of exponential decay 2% growth20% growth2% decay 0.2% decay5logb(y) + 4logb(x)logb(y^5+x^4)logb(y^5x^4(5+4) logb(y+x) logb(yx^5+4)3e^2x + 2 = 281.07970.46890.92612.1595I really need help with these three problems.Thank you in advance!

2% decayall 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 100Or more generally:((initial value - changed value) / initial value) X 100logb(y^5+x^4)You can't answer the third one without knowing the value of x....
