Consider the following function. f(x) = |x − 9| Find the derivative from the left at x = 9. If it does not exist, enter NONE. -1 Correct: Your answer is correct. Find the derivative from the right at x = 9. If it does not exist, enter NONE. none Incorrect: Your answer is incorrect. Is the function differentiable at x = 9?

Answer with Step-by-step explanation:

We are given that

when x<9

when

LHD

=

RHD

Hence, the function is not differentiable at x=9

50x5=$250

step-by-step explanation:

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
