Graphf(x)= 1x2 andg(x)=f(x)+3onthe 2 same set of axes. What can you say about the slopes of the tangent lines to the two graphs at the point x = 0? x = 2? Any point x = x0? B (b) Explainwhyaddingaconstantvalue,C,toanyfunc- tion does not change the value of the slope of its graph at any point. [Hint: Let g(x) = f(x) + C, and calculate the difference quotients for f and g.]
