Question

Make x the subject of the formula:
Y=3x^2+4

Answer 1

see explanation

Explanation:

given

y = 3x² + 4 ( isolate the term in x by subtracting 4 from both sides )

y - 4 = 3x² ( divide both sides by 3 )

`(y-4)/(3)` = x² ( take the square root of both sides )

`\sqrt{(y-4)/(3) }` = x, or

x =
`\sqrt{(y-4)/(3) }`
