Answer:
y = 3√(x+3) -2
Step-by-step explanation:
The given points seem to match those of (half) a parabola that opens to the right. The parent function would be ...
x = y^2
or ...
y = √x . . . . . gives the upper half of the parabola only
It seems to have a vertical expansion by a factor of 3 and a translation of the vertex from (0, 0) to (-3, -2). The transformed function is then ...
y = 3√(x +3) -2
_____
We have transformed the parent function using ...
y = a·f(x-h) +k
where <em>a</em> is the vertical expansion factor, <em>h</em> is the horizontal translation, and <em>k</em> is the vertical translation.
Given:
To find:
Solution:
Solving the equation (i):
Putting the value of x into the equation (ii):
Putting the value of y into the equation (i):
So, the value of

Answer: The predicted difference in sleep is 1251437 minutes.
Step-by-step explanation:
Since we have given that
Number of years of education = 12 years
Number of minutes a week = 2000
As we have
In case of individual A:
7 days = 2000 minutes
1 year = 365 days =
12 years =
In case of individual B:
7 days = 3000 minutes
1 year = 365 days =
16 years = minutes
So, the predicted difference in sleep between individuals A and B is given by
Hence, the predicted difference in sleep is 1251437 minutes.
