Math - PreCalc (12th Grade)

What is the slope of the tangent line passing through the point (2, 3) of the graph of this function?
so is it c?
ok so far, though they already told you that f(2)=3 because the point (2,3) is on the graph.
As you know, the slope at any point (x,y) on the graph is 2x+2
So, the slope at x=2 is 6
Though, if this is pre-calc, how do you know the slope of the tangent to a curve? That's actual calculus.
