Say I have the problem solved up to this point: 16x^10+28x^5+28x^5+59.

Do I add the powers of 5 or leave alone and just add the numbers?

take the ration of 2/1^3 or to be read 2/1 cubed.
(1= 220hz/ 2=440hz) to the third power or cubed.
This is in relation to the squaring and cubing of harmonic ratios. in this case an octave or a ratio of 2/1 is being squared and cubed.

I finished most of my hw except these problems. Please show work.
1) Find the limit:
lim x->infinity (x^4 +x^3)/(12x^3+128)

2) Find the limit:
lim x -> negative infinity e^(3t)inversesine(1/t)

3) If lim x->c (f(x)+g(x)) = 3 and lim x->c (f(x)-g(x)) = -1, find lim x->c f(x)g(x).

3) Find the limit and state if the function is continuous at the point being approached.

lim x->0+ sin((pi/2)e^(square root x)

4) Find a simple basic function as a left end behavior model and a simple basic function as a right end behavior model.

y = (2x^4 - x^3 + 2^x - 1) / (2 - x)

thank you very much!
