Consider the function f(x) = x2 – 331. Chivonne claims a domain restriction x ≥ 0 produces the inverse function f–1(x) = StartRo

ot x minus 331 EndRoot . Which statement describes whether Chivonne is correct? The expression for f–1(x) is correct, but the domain restriction is not. The domain restriction is correct, but the expression for f–1(x) is not. Both the expression for f–1(x) and the domain restriction are correct. Neither the domain restriction nor the expression for f–1(x) is correct.

Answer:

The correct option is;

The domain restriction is correct but the expression for f⁻¹(x) is not

Step-by-step explanation:

The expression for the function is given as follows;

f(x) = x² - 331

The inverse function suggested = f⁻¹(x) = √(x-331)

The domain restriction is x ≥ 0

The inverse function if given as follows;

y = x² - 331 (Interchange x and y to get)

x = y² - 331

x + 331 = y²

y = ±√(x + 331)

Given that the domain restriction has been put as x ≥ 0, we select the + case to give;

f⁻¹(x) = √(x + 331)

Therefore, the domain restriction is correct but the expression for f⁻¹(x) is not.

In your own words, explain the Normal Distribution and provide a real world example.
elena-14-01-66 [18.8K]

Answer:

The Normal distribution is a continuous probability distribution with possible values all the reals. Some properties of this distribution are:

Is symmetrical and bell shaped no matter the parameters used. Usually if X is a random variable normally distributed we write this like that:

X \sim N(\mu , \sigma)

The two parameters are:

\mu who represent the mean and is on the center of the distribution

\sigma who represent the standard deviation  

One particular case is the normal standard distribution denoted by:

Z \sim N(0,1)

Example: Usually this distribution is used to model almost all the practical things in the life one of the examples is when we can model the scores of a test. Usually the distribution for this variable is normally distributed and we can find quantiles and probabilities associated

Solve for m -mk-90>85
loris [4]
First add 90 to both sides) -mk>85+90simplify 85+90 to 175) -mk>175divide both sides by K) -m>175/kmultiply both sides by -1) m<-175/k
 YOUR ANSWER IS
M<-175/K

What is the area of this square the height is 4 in the width is 4
puteri [66]

Answer;

64

Step-by-step explanation:

eee 4*4*4=64

sorry if im wrong, since it's a square than all the sides are the same, if it is a 3d CUBE then the area is 64 but if you're talking about a 2d square then its 16
