Looking at the above work especially the absolute value sign and the squared-term you should also be thinking about negatives. Lets start with a simple TEST.

Negative ODD integer some negative value.
. Neither of the statements is true. Let X be a random variable that takes values between 0 and c only for some c0 so that P0Xc1. So the above rule tells us that x³ is negative and x² is positive.
F is differentiable at x2 III. Lim f x -2 x2 O f 2 -2 Olim f x lim f x x0 x0-1 lim f x does not exist. Suppose Then I isnt true because while the limit exists as and is equal to we have so is not continuous there.
Negative EVEN integer some positive value. A I only b II only c I and II only d I and III only e II and III only. At first glance this answer looks correct for the equation x2 y2 0 x 2 y 2 0.
If x 22 y 5 then which of the following must be true. Were asked which of the following MUST be true. Prealgebra questions and answers.
Eliminate Answers B and D. X 3 or x 2 and x 2 x. NO case make x -2 and we see -2 2 while -22 4 This one doesnt have to be true.
Log in to add comment. If x2 - 16 0 which of the following must be true. Shakespeares works were written to be preformed on stage TRUE FALSE 2.
For x2 Bx C x ax b 0 which of the following must be true. If c is the number that satisfies the conclusion of the MVT for fxx³-2x² on the interval 0x2 the c. O ab B and a b C O a b C and a b B ab B and a - b C O ab C and a b B.
The left hand side of the equation is a difference of two squares and may be factored out as follows. Calculus questions and answers. Because the only restriction is that xy 0 x y 0 this means that either x or y could be positive while the other is a negative.
From above x 2 9 when x 3. If x is an integer which of the following must be an even integer. X 2 x.
Given that x is defined as sqrtx2 then it follows that the number x must be greater than 1 -- that is the only cases where the square is smaller than the number itself are fractions between 0 and 1. So it must be true that x³ x². This MUST BE TRUE.
Buuuut then you had some questions about the quant sectionspecifically question 9 of the second. If fxsinx2 then there exists a number c in the interval. Therefore option E is correct.
X 2 5 x 5. E I II and III. Which of the following MUST be true.
II is also not true because is not differentiable at. X 22 x 4. Zimovet 89 11 months ago.
X 2 2 x 10. Select all correct answer choices. Which means the derivative does not exist at.
Xâ µ 1 - x. Suppose -2 f x x² - 4x 2 for all x 2. X 2 3 x 8.
Without knowing anything else about neither of these needs to be true. The following must be true. Learn more about limits and derivatives.
X 2 4 when x 2. F is continuous at x2 II. X 2 4 x 6.
So you were trying to be a good test taker and practice for the GRE with PowerPrep online. If 1 y x and 0 x which of the following must be true A 1 x y B 1 2 2 y x C 1 2 1 from MATH 1050A at The Chinese University of Hong Kong. X 2 x 1.
The derivative of f is continuous at x2. However we have to keep in mind that any number positive or negative when squared is positive. So X CAN be 2.
Hence x 2 9 or x 2 4. Determine whether each of the following statement is true ie always true or false ie not always true. The integral from a to b of fxdx the integral from a to b of fxdx.
