Find f(x) and g(x) so the function can be expressed as y = f(g(x)). y= <img src="https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7Bx%5E2%

lisabon 2012 [21]

Answer:

One possible answer is:

f(x) = (2/x) + 3 and g(x) = x².

Step-by-step explanation:

Explanation:

We are to write this equation as y = f(g(x)). This means we want it to be a composite of functions; in f(x), we take the value of g(x) and use in place of x.

If we let g(x) = x², this means everywhere we see an x in f(x), we will replace it with x². To make our equation y = 2/x² + 3, working backward we would substitute x for x²; this would give us f(x) = 2/x + 3.

A city has a population of 280,000 people. suppose that each year the population grows by 4.5% . what will the population be aft

Anastasy [175]

Given that population of the city is 280000.

Rate of growth of the population = r = 4.5% = 0.045

We have to find population after 15 years so time

t = 15

We can use growth formula to find the required population which is given by :

$A=P(1+r)^t$

Where P= starting population = 280000

r= rate of growth = 0.45

t= time = 15

now plug these values into above formula.

$A=280000(1+0.45)^{15}$

$A=280000(1.45)^{15}$

$A=280000(263.34194176)$

$A=73735743.6928$

Hence population after 15 years will be approx 73735743.
