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>
Step-by-step explanation:
5x + 7 = 2
=> 5x = 2 - 7
=> 5x = -5
=> x = -5/5
=> x = -1
=> x = -1.000 ( to the nearest thousandth)
