Answer:

f^{-1}(x)=\sqrt{\frac{1}{8}(-x+4)}

Step-by-step explanation:

Given function is,

f(x) = -8x² + 4

Step to find the inverse of the function,

Step 1

Write the function in the form of an equation,

y = -8x² + 4

Step 2

Interchange the variables 'x' and 'y',

x = -8y² + 4

Step 3

Solve the equation for y,

x = -8y² + 4

x - 4 = -8y²

-x + 4 = 8y²

y² = \frac{1}{8}(-x+4)

y=\sqrt{\frac{1}{8}(-x+4)}

Therefore, inverse of the function f(x) will be,

f^{-1}(x)=\sqrt{\frac{1}{8}(-x+4)}

Andru [333]

Answer:

91.99%

Step-by-step explanation:

To find what percentage of $7599 is $6990, we simply need to divide $7599 by $6990 and multiply by 100:

6990 / 7599 * 100 = 91.99%

Therefore, they paid 91.99% of the original price.
