Answer:

The inverse of the given relation is  [tex]x=\sqrt{\frac{y+3}{7}}[/tex] .

Step-by-step explanation:

Given:

y=7x² - 3

Now, to find the inverse of the given relation.

[tex]y=7x^2-3[/tex]

So, adding both the sides by 3 we get:

[tex]y+3=7x^2[/tex]

Now, dividing both the sides by 7 we get:

[tex]\frac{y+3}{7} =x^2[/tex]

And, using square root on both the sides we get:

[tex]\sqrt{\frac{y+3}{7}} =x[/tex]

Thus:

[tex]x=\sqrt{\frac{y+3}{7}}[/tex]

Therefore, the inverse of the given relation is  [tex]x=\sqrt{\frac{y+3}{7}}[/tex] .
