Question
+ 14 if z < 8
x + 14
Analyze the function f (x) =
8 x
+ 10 if x > 8
Your classmates may be analyzing different functions, so in your initial post in Brightspace be sure to specify the function that you are analyzing.
Part 1: Is f (x) continuous at x
= 8? Explain why or why not in your Discussion post
Yes
No
Hint: In order for f (x) to be continuous at x = 8, the limits of f (x) from the left and from the right must both exist and be equal to f (8).
Part 2: Is f (x) differentiable at x = 8? Explain why or why not in your Discussion post.
Yes
No
Hint: Similarly to continuity, in order for f (x) to be differentiable at x =
f(8+h)–f(8)
= 8, f (x) must be continuous at x = 8 and the limits of the difference quotient
from the left and from the right must both exist and be equal to each other.
