inverse for x is negative

well, since x is squared, it doesn't matter snce (-)^2=(+)

inverse

replace f(x) with y

solve for x

replace x with f invers aka f⁻¹(x) and y with x

y=6x^2+4

minus 4

y-4=6x^2

divide 6

(y-4)/6=x^2

squaer root both sides

[latex] \sqrt{ \frac{y-4}{6} } [/latex]=x

replace x with f⁻¹(x) and replace y with x

f⁻¹(x)=[latex] \sqrt{ \frac{x-4}{6} } [/latex]
