Question

What is the inverse of the given function? y = 7x2 -­ 3?

Answer 1

y = ± √x + 3/7 is the answer 100% sure

Answer 2

y = ±
`√((x+3)/7)`

Explanation:

Given: y = 7x^2 - 3

To find inverse function follow the steps.

Step 1: Replace x by y and y by x, so w get

x= 7y^2 - 3

Step 2: Write y interms of x.

7y^2 = x + 3

Dividing both sides by 7, we get

y^2 = (x + 3)/7

To find y, take the square root on both sides

y = ±
`\sqrt{(x+3)/(7) }`

Hope this will helpful.

Thank you.
