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>
Answer:
The answer of your question is:
Step-by-step explanation:
Solve p² + 4p = 1
p² + 4p + (2)² = 1 + (2)²
(p + 2)² = 1 + 4
(p + 2)² = 5
(p + 2) = ±√5
p1 + 2 = √5 p2 + 2 = -√5
p1 = √5 - 2 p2 = -√5 + 2
p1 = 0.23 p2 = -0.23
