Answer:
its below
Step-by-step explanation:
a) (0,1) (-1,2) (1,2) (2,5) (-2,5)
b) (0, -1, 1, 2, -2)
c) (1,2,5,5)
#4 a) f(-5) = 39
b) f(1) = -9
Answer:
84 couples
Step-by-step explanation:
First add the number of couples that have only one spouse that prefers dramas.
23+39+37+27=126
126 couples out of 250 prefer dramas.
126/250=.56 or 56 percent
To find the answer by making a prediction based on this data, you would find 56% of 150.
150x.56=84 out of the additional 150 surveyed couples will have one spouse that prefers a drama.
The domain is the set of allowed x inputs, or x coordinates of a function. In this case, any point on the curve has an x coordinate that is 4 or smaller.
Therefore, the domain is the set of numbers x such that 
To write this in interval notation, we would write ![(-\infty, 4]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C%204%5D)
This interval starts at negative infinity and stops at 4. We exclude infinity with the curved parenthesis and include 4 with the square bracket.
-----------------------------------------------------------------------
The range is the set of possible y outputs. Every point on this curve has a y coordinate that is either 0 or it is larger than 0.
The range is the set of y values such that 
In interval notation, it would be written as 
This time we start at 0 (including this endpoint) and "stop" at infinity
note: we always use curved parenthesis at positive or negative infinity because we cannot reach either infinity
The answer is g(x) = 2^x+3-2
A. yes this is a statistical question. it is a statistical question because you can answer the question by collecting data.
b. some clusters are.. 3,4,5, and 6 they are clusters because they are assembled around a particular value. the peak is 6 because it is the highest number it reaches. there are no gaps in this table.
c. to calculate the average with a graph you sum the numbers then divide by the total number of values in the set. for this table you add 1+2+3+3+4+4+4+5+5+5+5+5+5 then you divide by 15.
1+2+3+3+4+4+4+5+5+5+5+5+5=51
51 ÷ 15= 3.4
