Q. 5

Question

In our proof that constant functions are continuous, we used the fact that given any  > 0, a choice of any δ > 0 will work in the formal definition of limit. Use a graph to explain why this makes intuitive sense. (This exercise depends on Section 1.3.)

Answer

Graph



1Step 1. Given information

Constant functions are continuous.

2Step 2. Graph

For example, take a constant function limx->4(2x+1)=9 , take δ = 0.5 then it looks right for =1.


The figure is shown below :-
