The inverse of an equation is the opposite of the equation

The inverse of the function is y =2 \pm  \sqrt{28 + 4x

<h3>How to determine the inverse of the function </h3>

The equation is given as:

2(x - 2)^2 = 8(7 + y)

Divide both sides of the equation by 2

(x - 2)^2 = 4(7 + y)

Open the bracket

(x - 2)^2 = 28 + 4y

Take the square roots of both sides

x - 2 = \pm\sqrt{28 + 4y

Add 2 to both sides

x =2 \pm  \sqrt{28 + 4y

Swap the occurrences of x and y

y =2 \pm  \sqrt{28 + 4x

Hence, the inverse of the function is y =2 \pm  \sqrt{28 + 4x

Answer:

Step 3 contains error.

Step-by-step explanation:

The given equation is :

\dfrac{1}{4}(\dfrac{1}{3}k+9)=6

Step 1.

Cross multiplying,

(\dfrac{1}{3}k+9)=24

Step 2.

Subtract 9 from both sides

\dfrac{1}{3}k+9-9=24-9\\\\\dfrac{1}{3}k=15

Step 3.

Cross multiplying

k=15\times 3\\\\k=45

So, there is an error in step 3. The correct answer should be 45.
