Hi,
f°g means : apply first g then f . so calculate "g" and then use result as "x" in f.
g°f means : you apply first f then g
so : f°g = 2(3x²-x) -5 = 6x²-2x- 5
To improve in math, you need practice. have a try with g°f :)
give the answer in comments, and I will tell you if you are correct.
good luck.
Answer:
<h2>g = 7</h2><h2 />
Step-by-step explanation:
5.1g = 35.7 divide by 5.1 each side
g = 35.7 / 5.1
g = 7

Answer:
Required solution gives series (a) divergent, (b) convergent, (c) divergent.
Step-by-step explanation:
(a) Given,
To applying limit comparison test, let and . Then,
Because of the existance of limit and the series is divergent since where , given series is divergent.
(b) Given,
Again to apply limit comparison test let and we get,
Since is convergent, by comparison test, given series is convergent.
(c) Given,
. Now applying Cauchy Root test on last two series, we will get,
- \lim_{n\to \infty}|(\frac{5}{6})^n|^{\frac{1}{n}}=\frac{5}{6}=L_1
- \lim_{n\to \infty}|(\frac{1}{3})^n|^{\frac{1}{n}}=\frac{1}{3}=L_2
Therefore,
Hence by Cauchy root test given series is divergent.
