What is the inverse of the function f(x) = 2x + 1?

BaLLatris [955]

Answer:

$f^{-1} = \frac{x-1}{2}$

Step-by-step explanation:

$f(x) = 2x+1$

<em>Replace it with y</em>

$y = 2x+1$

<em>Exchange the values of x and y</em>

$x = 2y+1$

<em>Solve for y</em>

$x = 2y+1$

<em>Subtracting 1 from both sides</em>

$2y = x-1$

<em>Dividing both sides by 2</em>

$y = \frac{x-1}{2}$

<em>Replace it by </em> $f^{-1}$

So,

$f^{-1} = \frac{x-1}{2}$

I really need help, someone please help me

Hoochie [10]

Answer:

18.84 meters.

Step-by-step explanation:

The formula for a circle is πr^2.

πr^2 = 28.26

3.14 * r^2 = 28.26

r^2 = 9

r = plus or minus 3.

But since this deals with the area of a circle, there is no way a radius can be negative. So, the radius is 3 meters.

The formula for the circumference is 2πr.

2 * 3.14 * 3 = 6 * 3.14 = 18.84.

So, the circumference of the circle is 18.84 meters.

Hope this helps!
