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

BaLLatris [955]

Answer:

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

Step-by-step explanation:

$f(x) = 2x+1$

Replace it with y

$y = 2x+1$

Exchange the values of x and y

$x = 2y+1$

Solve for y

$x = 2y+1$

Subtracting 1 from both sides

$2y = x-1$

Dividing both sides by 2

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

Replace it by $f^{-1}$

So,

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

? 2 to the 3rd power - 5 x (6 + 4) ÷ 2 show your work

Delvig [45]

Answer:

-17

Step-by-step explanation:

$2^3$ - 5 * (6 + 4) ÷ 2

Following PEMDAS, we must focus on the parenthesis first.

$2^3$ - 5 * (6 + 4) ÷ 2

$2^3$ - 5 * (10) ÷ 2

Now we will focus on the exponent:

$2^3$ - 5 * 10 ÷ 2

8 - 5 * 10 ÷ 2

Now Multiplication/Division.

This is where you must follow the order in the equation where you see the multiplication sign first, so you multiply first.

8 - 5 * 10 ÷ 2

8 - 50 ÷ 2

Next, Divide:

8 - 50 ÷ 2

8 - 25

Subtract:

8 - 25

-17

$2^3$ - 5 * (6 + 4) ÷ 2 = -17.
