Please I really need help in Algebra 2 I WILL give medals and become a fan!
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!

So for number 1:
2%=0.02=1-0.02=0.98,
So its exponential decay 2%, which is c.
Did you understand that part?

anonymous · Answer

And for 2.
logby^5+logbx^4
logb(y^5x^4) so b
For 3
3e^2x + 2 = 28 
x=2.1595
so d.

@zeinas. Hey thanks I really appreciate the help!

anonymous · Answer

You're welcome. :)

@zeinas. could you help me with this one?

anonymous · Answer

5logb(y) + 4logb(x)

anonymous · Answer

Sure. It's:
logby^5+logbx^4
logb(y^5x^4) 
It's the same as the second question before.
