Answer:
Step-by-step explanation:
<h3>Given</h3>
- f(x) =

<h3>To find </h3>
<h3>Solution</h3>
<u>Change f(x) → x, and x → y, and solve for y:</u>
- x =

- x² = 7y - 21
- 7y = x² + 21
- y = 1/7x² + 3
<u>y = f⁻¹(x)</u>

They didn’t use a ruler I think they made their own materials from what they had. Also thank you.
X(x-20)=12000
x^2 - 20x = 12000
x^2 - 20x - 12000 = 0
(x - 120)(x + 100) = 0
x = -100, 120
so the width is 120 ft
