Is the Mean Value Theorem applicable to the function f(x) = |x - 1| on the interval [0, 2]?Why or why not?

Answers

The only point that derivative of the function f(x) = |x - 1| is not continuous is at x = 0. You need to check whether the slope for the interval (0,2) is continuous to see if you can apply MVT. The interval (0,2) does not include end points, so 0 is not in this interval. The function is continuous over the interval, so MVT can be applied.

A is 30% of b. b is 90% of c. what % of c is a

Answers

A = 30% of B = 0.3B
B = 90% of C = 0.9C

A = 0.3(0.9C) = 0.27C = 27% of C

What is the slope of line segment E F?
A)1/3
B)3/2
C)2/3
D)-3/2

Answers

Step-by-step explanation:

the picture even tells you the formula.

what ? you cannot do these simple subtractions yourself ? what don't you understand there ? please tell me, so that I can help you with that.

as the formula says, the slope is y difference / x difference between the 2 points.

E = (-2, -4)

F = (2, 2)

for the difference calculation it is just important that you do both in the same direction.

x difference = 2 - -2 = 4

y difference = 2 - -4 = 6

so the slope is 6/4 = 3/2

therefore, B 3/2 is the correct answer

that's it. that is all there was to this.

FYI - the slope indicates how many units y changes, when x changes a certain amount of units when you go from one point on the line to another.
