Find, then state if it’s a function
valentina_108 [34]

Answer:

The answer is y = ± \sqrt[4]{\frac{x}{4}} ,  f^{-1}(x) is a function ⇒ 1st answer

Step-by-step explanation:

Let us revise the steps of find the inverse of a function

  1. Replace f(x) with y
  2. Replace every x by y and replace y by x
  3. Solve the equation in Step 2 for y
  4. Replace y by f^{-1}(x)

∵ f(x)=4x^{4}

- Replace f(x) by y

∴ y=4x^{4}

- Replace y by x and x by y

∴ x=4y^{4}

- Divide each side by 4

∴ \frac{x}{4}=y^{4}

- Take \sqrt[4]{}  for both sides

∴ ± \sqrt[4]{\frac{x}{4}}=y

- Switch the two sides

∴ y = ± \sqrt[4]{\frac{x}{4}}

∵ There is no fourth root for negative number

∴ x ≥ 0

When you test the graph of f^{-1}(x) by a vertical line, it will cut it just at one in every position, so it is a function. Look to the attached graph for more understand

∴  f^{-1}(x) is a function

The answer is y = ± \sqrt[4]{\frac{x}{4}} ,  f^{-1}(x) is a function

An architect designs a rectangular flower garden such that the width is exactly​ two-thirds of the length. of 350350 feet of ant
ozzi
For this problem, the total length of fencing is equivalent to the perimeter of a rectangle. The formula for the perimeter of a rectangle is written below:

P = 2L + 2W
where L and W are the length and width dimensions

From the relationship described,
P = 350,350 ft
W = 2/3 L
Substituting this to the perimeter equation:

350,350 = 2L + 2(2/3 L)
Solving for L,
L = 105,105 ft
W = (2/3)(L) = (2/3)(105,105) = 70,070 ft
