PLEASE HELP ME FAST!

Answer:

From <u>fourth</u> month onwards, the growth rate of f(x) is greater than that of g(x).

Step-by-step explanation:

Given:

The growth rates of both bank accounts are given as:

f(x)=3^x\\g(x)=5x+25

Now, as per question, we need to find the value of 'x' when the value of f(x)>g(x). Or,

3^x>5x+25

Now, we can do this by checking the values of 'x' by hit and trial method.

Let x=1. The inequality becomes:

3^1>5(1)+25\\3>30(False)

Let x=2. The inequality becomes:

3^2>5(2)+25\\9>35(False)

Let x=3. The inequality becomes:

3^3>5(3)+25\\27>40(False)

Let x=4. The inequality becomes:

3^4>5(4)+25\\81>45(True)

Therefore, the value of 'x' for which f(x)>g(x) is 4.

So, from the fourth month onwards, the balance in f(x) becomes greater than g(x).

The graphical solution is shown below to support the same.

From the graph, we can conclude that after the 'x' value equals 3.4, the graph of f(x) lies above of g(x). Hence, f(x)>g(x) for x>3.4

How do u do exponents<br>​
Gelneren [198K]

Answer:

Step-by-step explanation:

The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents. In this example, you can see how it works. Adding the exponents is just a short cut! The "power rule" tells us that to raise a power to a power, just multiply the exponents.
