$\frac{n}{3}$ +6 - 7 = 4
Subtract 6 from each side of the equation

$\frac{n}{3}$ -7 = -2

Now add 7 to both sides of the equation.

$\frac{n}{3}$ = 5

Finally multiply by 3 on both sides to undo the division

n= 15

Check
15/3 + 6 -7 = 4
5 + 6 -7 = 4
11- 7 = 4
4 = 4

The total value of the account is based on the function f(x) = q • 1.025x, where x represents the number of years the money has

Harman [31]

Would it not just be q? Since I am assuming that 1.025 is the interest rate of the bank hence why it would be multiplied by the year.

Determine f^-1(2) given the following: f(1 = -3f(2) = -2f(-1) = 2f(3) = -1

lana [24]

We assume that the function is as follows:

$f^{-1_{}}(2)=?$

Then, we have that:

$f^{-1}(x)=\frac{1}{f(x)}$

Thus, if we have that:

$f(2)=-2\Rightarrow f^{-1^{}_{}}(x)=\frac{1}{f(x)}\Rightarrow f^{-1}(2)=\frac{1}{f(2)}=\frac{1}{-2}\Rightarrow f^{-1}(2)=-\frac{1}{2}$

Therefore, the value for the function is f^-1(2) = -1/2 or

$f^{-1}(2)=-\frac{1}{2}$
