Given:

f(x) is continuous, f(3)=1,f(1)=6,f(6)=-2,f(-2)=3.

To find:

The value of \lim_{x\to 6^+}f(x) and \lim_{x\to -2^-}f(x).

Solution:

If a function f(x) is continuous at x=c, then

\lim_{x\to c^-}f(x)=f(c)=\lim_{x\to c^+}f(x)

It is given that the function f(x) is continuous. It means it is continuous for each value and the left-hand and right-hand limits are equal to the value of the function.

The function is continuous for 6. So,

\lim_{x\to 6^-}f(x)=f(6)=\lim_{x\to 6^+}f(x)

\lim_{x\to 6^+}f(x)=f(6)

\lim_{x\to 6^+}f(x)=-2

The function is continuous for -2. So,

\lim_{x\to -2^-}f(x)=f(-2)=\lim_{x\to -2^+}f(x)

\lim_{x\to -2^-}f(x)=f(-2)

\lim_{x\to -2^-}f(x)=3

Therefore, \lim_{x\to 6^+}f(x)=-2 and \lim_{x\to -2^-}f(x)=3.

Answer:

b. Pearson's correlation can be used in the same way as it is for linear relationships

Explanation:

Pearson's correlation can also be termed "simple linear regression analysis" is a statistical measure used to determine if two numeric variables are significantly linearly related. Pearson's correlation coefficient is used to measures the statistical relationship or association between two continuous variables.

21x - 19 = 3x + 17   |add 19 to both sides
21x = 3x + 36    |substract 3x from both sides
18x = 36     |divide both sides by 18
x = 2

vladimir1956 [14]

Answer:

J(t) = 230,600(1.009)^t

Step-by-step explanation:

J(t) = 230,600(1 + 0.009)^t, or

J(t) = 230,600(1.009)^t
