How do you get the vertex of this absolute value? y = -2 |4x - 1| + 16 By vertex you mean the highest point. Find out where the expression inside the absolute value is 0. Since the absolute value is always positive, in this expression some quantity is being subtracted from 16...

How to find the exact value of lim (2^h - 1)/ h h->0 Thanks in advance. If you use lim dx->0 of [f(a + dx) - f(a)]/dx = f'(a) and recognize 1=2<sup0. Then use f(x)=2x Thus lim dx->0 [20+dx - 2<sup0]/dx = f'(0). This means find d/dx 2x and evaluate at x=0. You ...

mean value theorem
Show that the function f(x)=1-|x|, [-1,1] does not satisfy the hypotheses of the mean value theorem on the given interval. Also how do I graph the function together with the line through the points A(a,f(a)) and B(b,f(b)). Also how do I find values of c in (a,b) that satisfy f...

I'm having some troubles with these. Thanks in advance. If a>0 find the minimum value. If a<0 find the maximum value. 1. y=-x²+2x+5 2. y=-2x²-3x+4 These are functions for parabolas, so f(x)=ax²+bx+c when a does not equal 0 In both your examples, the "a", which is the ...

The geometric mean of two postitive numbers a and b is sqrt(ab). Show that for f(x) = 1/x on any interval [a,b] of positive numbers, the value of c in the conclusion of the mean value theorem is c = sqrt(ab) I have no idea how to do this! If the mean of a and b is sqrt(ab), ...

Calc, Mean Value Theorem
Consider the function : 3x^3 - 2x^2 - 4x + 1 Find the average slope of this function on the interval. By the Mean Value Theorem, we know there exists a "c" in the open interval (-2,3) such that f'(c) is equal to this mean slope. Find the two values of "c" in the interval which...

A coin is biased such that a head is thrice as likely to occur as a tail. Find the probability distribution of heads and also find the mean and variance of the distribution when it is tossed 4 times. P(head) + P(tail) = 1 P(head) = 3 P(tail) Solving gives: P(head) = 3/4 If we ...

math- mean value theorem
Hi I am having some trouble with these few quetions I would appreciate some help so that I can understand them better. 1) What, if anything, does the mean value theorem guarantee for the given function on this interval? a) f(x) = x^2 - 2x + 5 on [1,4] --I am a bit uncertain on...

stats:find the mean
If you want the mean salary, you can only get an approximate value since you only have histogram data (the number per salary interval). Assume that the number 16 applies to a salary at the midpioit of the first interval ($7500), etc. The mean will be (16*7500 + 15*12500 + 11*(...

The mean value theorem states that a continuous function between x=a and x=b will have at least one tangent parallel to the chord AB. For f(x)=(1-x)³, the chord between 0 and 3 has a slope of s=(f(3)-f(0))/(3-0)=-3 The value(s) of c required must satisfy f'(c)=-3 So, ...

Pre-Calc : Find the Exact Value of the Expression
Find the exact value of the expression without a calculator: sin(3π/4+5π/6) I've done: sin(9π/12 + 10π/12) =sin(19π/12) What do I do now? Im confused if that would just be the answer or what? Wouldnt the answer be numerical?
