F(x) = x² - 81
Finding f⁻¹(x) the inverse function
Let y = f(x) and solve for x.
y = x² - 81
y + 81 = x²
x² = y + 81
x = √(y + 81)
Recall f(x) = y, that means x = f⁻¹(y)
x = √(y + 81)
f⁻¹(y) = √(y + 81)
Therefore f⁻¹(x) = √(x + 81)
Solving for y means to get that variable on one side of the equation and everything else needs to be on the opposite side of y.
We also know x is equal to 28. So, we can replace x with 28.
Now the equation will look something like 28 + 3y = 28
Now let us solve it.
28 + 3y = 28
First, subtract 28 from each side of the equation.
(28 + 3y) - 28 = 28 - 28 =
3y = 0
Now divide each side by 3.
3y / 3 = 0 / 3
y = 0/3
If a fraction has a numerator of 0, that means it's 0.
So, y is equal to 0.

Please look at the image
From the info 2 jars with 106 sprinkles each, we know 1 jar would have 53 sprinkles.
1 jar has 53 sprinkles.
6 jars have 318 sprinkles because:
6 × 53 = 318
13 jars have 689 sprinkles because:
13 × 53 = 689
Answer:
I don't know the exact answer but the correct answer would be A(Then, unknown value)E I think.
Step-by-step explanation:
The reason why is because it would make a square if you put the answer and ADE together.

THIS COULD BE WRONG</h2>
2.5% of 15,00$ would be 375$. Assuming the "simple interest" is yearly, you would multiply 375 by 8, which is 3000$ :P (Another way to solve this would be to multiply the 2.5 by 8, which would be 20. and 20% of 15,000$ would also be 3,000$)
