The coefficiient of the first term  ( the -3). AS its negative the grph starts at top left.

The coefficient of the first term. 
If it's talking about the left end, then it'll be the first degree. So since it's to the third power, you'll have something that looks like x^3, which starts at the bottom left. The negative sign indicates a swapped axis. So it'll be the coefficient (which is -3). That states it'll start from the top left and go downward. The +3 is just a vertical shift.

What is the inverse of the function? f(x)=3^x−1
geniusboy [140]

y = f(x) = 3^{x} - 1

let x be y and y be the x, so we have

x = 3^{y} - 1

3^{y} = x + 1

log_{3}(3)^{y} = log_3(x + 1)

y = log_{3}(x+1)

The correlation analysis assumes that the measurements have a bivariate normal distribution in the population. Select all of the
RoseWind [281]

Answer:

A. True

B. True

C. False

D. False

E. False

F. False

G. True

Step-by-step explanation:

Select all of the features that define a bivariate normal distribution.

<em>(this means that we select only those that are properties of the bivariate normal distribution)</em>

A. Bell-shaped probability distribution in two dimensions rather than one

<em>TRUE  because any combination of the two is still normal Z(x,y)=aX+bY</em>

B. A relationship between X and Y that is not linear

<em>TRUE The contours of the distribution are ellipses.</em>

C. The presence of outliers

<em>FALSE possible, but not always.</em>

D. Either X or Y has a decidedly skewed distribution

<em>FALSE normal distributions are symmetric</em>

E. A relationship between X and Y that is linear

<em>FALSE see answer to B</em>

F. A cloud of points that is funnel shaped (wider at one end than the other)

<em>FALSE normal distributions are symmetric</em>

G. The frequency distributions of X andY separately are normal

TRUE For example, in <em>Z(x,y)=aX+bY, putting a or b=0 means that X and Y separately are normal.</em>
