Very basic calculus question - do you think there's a typo? I'm helping someone with their homework before they go back to A-Levels, and I came across the following question which I think is miswritten:

Find the gradient at $x=1$ of the equation $y=3x^2-1$' which is obviously $6$

The follow-up question is:

Hence find the equation of the line parallel to the tangent through the point $(-1,1)$'

I notice that the point $(-1,1)$ doesn't lie on the equation of the curve. Do you think this is a typo? And that they actually originally wanted us to find the gradient at $x=-1$.
The answer given as correct is $y=6x+7$.

The tangent has slope $6$.  The line they want is parallel to the tangent, and goes through $(-1,1)$
