Talib is trying to find the inverse of the function to the right. His work appears beneath it. Is his work correct? Explain your

Rasek [7]

To find the inverse of a function, we make the independent variable the subject of the formula.

Thus, the inverse of the given function is evaluated as follows.
$f(x)=-8x+4 \\ y=-8x+4 \\ -8x=y-4 \\ x= \frac{y-4}{-8} \\ f^{-1}(x)=\frac{x-4}{-8}$

From the work show, it can be seen that Talib's work is correct.

Firdavs [7]

Answer:

6.3 feet

Step-by-step explanation:

use pythagorean theorem

a² + b² = c²

a² + 3² = 7²

a² + 9 = 49

Subtract 9 from both side

a² = 40

Take the square root of both sides

a = 6.324555320336759

Rounded

a = 6.3
