## Help again?

Hi again,

Still doing my revision and have come across some questions which have me stumped.

3. Find the equation of the tangent to the curve y = x√2x2 + 7 at x = 3.

I got y=15+8.6*(x-3) -. Am i correct?

I have attatched 2 questions as images,

Thanks in advance for any help,

Regards.
