Let f(x) = y

y = 2^x

x = 2^y

Solve for y.

ln x = ln(2^y)

ln x = y ln 2

ln x/ln 2 = y

Replace y with f^(-1) x.

f^(-1) x = ln x/ln 2

We now know f(x) and f^(-1) x.

Use your graphing calculator to graph the function and its inverse on the same xy-plane. If you don't have a graphing calculator, use DESMOS online.

Good luck.

BabaBlast [244]

Answer:

The minimum number of words left to write is 215

Step-by-step explanation:

Let

w -----> the number of words left to write

we know that

The number of words left to write plus the words written so far must be greater than or equal to 500 words

Remember that the word "at least" means "greater than or equal to"

w+285\geq 500

Solve for w

Subtract 285 both sides

w\geq 500-285\\w\geq 215

The minimum number of words left to write is 215

dusya [7]

Answer:

third option is the correct

Step-by-step explanation:

A function is "odd" when f (-x) = - f (x) for all x. ... For example, functions like

  • f (x) = x3,
  • f (x) = x5,
  • f (x) = x7, ... are odd functions.

Alicia earned d dollars baby-sitting. Her friend earned twice as much. You earned $2 less than Alicia's friend earned. Write an
Semenov [28]

Answer:

Total = \$5d - 2

Step-by-step explanation:

Represent Alice with A, her friend with F and you with Y.

From the question, we have:

A = \$d

F = 2 * A --- Twice as much Alice means 2 times Alice's earnings

Y = F - 2 --- 2 less than her friend

Required

Determine the total amount

A = \$d

Substitute \$d for A in F = 2 * A

F = 2 * \$d

F = \$2d

Substitute \$2d for F in Y = F - 2

Y = \$2d - 2

The total amount is calculated by adding the earnings of Alice, her friend and you

Total = A + F + Y

Total = \$d + \$2d + \$2d - 2

Total = \$5d - 2

<em>Hence, the total earnings is 5d - 2</em>
