Please can someone answer this for me, ive asked so many questions on here and they never get answered, I need the help rn this is like the last thing I can think of Given f(x) = ax – b, what is f-1(x)?
A) x - b a
B) x + b a
C) 1 ax - b
D) 1 ax + b

Answers

Answer 1
Answer:

Answer:

D

Step-by-step explanation:

So we have the function:

f(x)=ax-b

And we want to find its inverse.

To find the inverse of a function, we need to: 1) change f(x) and x, 2) change f(x) to f⁻¹(x), and 3) solve for f⁻¹(x) for the inverse.

So, flip f(x) and x:

x=a{f(x)-b

Change:

x=a {f^(-1)(x)-b

Solve. Add b to both sides. The right side cancels:

x+b=a{f^(-1)(x)

Divide both sides by a:

f^(-1)(x)=(1)/(a)(x+b)

So, our answer is D.

Which of the following are characteristics of the correlation coefficient? Check all that apply.

A. It must be between -1 and 1.
B. It must be positive.
C. It indicates the percentage of points that lie on the regression line.
D. The correlation coefficient tells you how strong the residuals are.
E. If correlation is positive, the slope of the regression line is also positive

Answers

This is about knowledge between Correlation and Regression.

Option A and E are correct.

  • Correlation Coefficient is the statistical relationship that exists between two variables. Let us look at the options;

Option A; Under different types of correlation coefficient they tend to make use of different range for their definitions but it is always between minimum of -1 and maximum of 1. Thus, the statement is correct.

Option B; It must not be positive because as stated in option A above negative values can be used.

Option C; No, it doesn't indicate percentage of points because in the definition i gave earlier, there is nothing like that. Besides, this is in regression and not correlation.

Option D; This is incorrect as the definition doesn't support it.

Option E; This is correct because positive correlation means that the two variables increase at the same time or decrease at the same time. Thus, it means the regression line will be positive as long as correlation is positive.

Equation of the line passing through the points 4,11 and -1,-14

Answers

Answer: y = 5x -9

Step-by-step explanation:

first grt slope:

m = rise / run

m = (11- -14) / (4 - -1)

m = (25) / (5) = 5

y - 11 = 5* (x - 4)

Y = 5x -9
