Keith used the following steps to find the inverse of f, but he thinks he made an error. Step 1. f(x) = 7x + 5 given

Step 2. y = 7x + 5 change f(x) to y

Step 3. x = 7y + 5 switch x and y

Step 4. x + 5 = 7y + 5 add 5 to each side

Step 5. x + 5 = 7y divide each side by 7

Step 6. x + 5/7 = y change y to g(x)

Step 7. g(x) = x + 5/7 switch sides of the equation

Given are five observations for two variables, x and y. xi 1 2 3 4 5 yi 3 7 5 11 14 which of the following is a scatter diagrams accurately represents the data? what does the scatter diagram developed in part (a) indicate about the relationship between the two variables? try to approximate the relationship betwen x and y by drawing a straight line through the data. which of the following is a scatter diagrams accurately represents the data? develop the estimated regression equation by computing the values of b 0 and b 1 using equations (14.6) and (14.7) (to 1 decimal). = + x use the estimated regression equation to predict the value of y when x = 4 (to 1 decimal). =
