Answer:

2

Step-by-step explanation:

It is not 7, although that looks possible. The 7 is a coefficient (in my day we called it a numerical coefficient).

The constant is not d either. That is a variable.

The constant is the 2

Which function below is the inverse of f(x) = x2 − 25?

Viktor [21]

$f(x) = x^{2} - 25$
Let f(x) = y
thus y = $x^{2} - 25$
switch the position of y and x in the equation
$x = y ^{2} - 25$
then solve for y in this case
$x + 25 = y^{2} 
$
∴ y= $\sqrt{x + 25}$

Thus, $f^{-1} (x) = \sqrt{x + 25}$

Answer:

$B) \sqrt{2}$ ÷ $2\sqrt{5}$

Step-by-step explanation:

$A$ → $2\sqrt{5}$ ÷ $\sqrt{5}$

$= \frac{2\sqrt{5} }{\sqrt{5} }$

<u>→ </u><u>2</u><u> is a rational number</u>

$B)$ → $\sqrt{2}$ ÷ $2\sqrt{5}$

$=\frac{\sqrt{2} }{2\sqrt{5} }$

$=\frac{\sqrt{2} }{\sqrt{2}*\sqrt{2}*\sqrt{5} }$

$= \frac{1}{\sqrt{10} }$

<u>↑ is irrational number</u>

$C)$ $\frac{\pi }{2}$ ÷ $\pi$

$= \frac{\pi }{2} *\frac{1}{\pi }$

$=\frac{1}{2}$

<u>↑ is a rational number</u>

$D)$ $5\pi$ ÷ $\pi$

$= 5$

<u>↑ is a rational number</u>

<u>So,</u><u> Option B</u><u> is your answer</u>

hope it helps..

have a great day!!!
