# I need help with this whole problem really

**Question description**

The point P(1,3) lies on the graph f(x)=x^2+x+1. Consider the point Q(x,f(x)) on the graph f, and let m*pq *be the slope of the secant line through the points P and Q.

a) find the equation for m*pq*

b) find limit as x approaches 1 for m*pq*. What does this limit mean in the context of this problem?

c) Find the equations of the tangent line and the normal line through the point P(1,3)
