Answer:
y = ±[tex]\sqrt{(x+3)/7}[/tex]
Step-by-step 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 = ±[tex]\sqrt{\frac{x+3}{7} }[/tex]
Hope this will helpful.
Thank you.
