a

What are the coordinates of the point at which $g\left(x\right)$g(x) is a tangent to the curve $f\left(x\right)$f(x)?

Note that this point has integer coordinates. Give your answer in the form $\left(a,b\right)$(a,b).

b

What is the gradient of the tangent line?

c

Hence determine the equation of the line $y=g\left(x\right)$y=g(x).
