What is the equation of the tangent line passing through the point (1, 3) of the graph of the function f(x) = x2 + x + 1?

ANSWER

EXPLANATION

The given function is

To find the gradient function, we find the first derivative;

To find the gradient at (1,3), we put x=1 into the gradient function to get;

The equation of the tangent line is

We substitute the point and the slope to get,

This simplifies to

y=3x
