Answer:
Step-by-step explanation:
W have been given that the vertex of a parabola is at (2, 3) and the point (0, -1) is also on the parabola. We are asked to find the equation of parabola in the form 
.
We know that vertex form of parabola in form 
, where (h,k) in vertex of parabola.
Upon substituting coordinates of vertex, we will get:
To find the value of a, we will substitute coordinates of point (0, -1) as:
Therefore, our required equation would be .
6x+4=4x-2 subtract four x to get 2x+4=-2 and subtract 4 and get -6 and divide it by two to get -3

The residual plot does not show a linear model and the estimated GPA of a student who studies for 15 hours a week is 3.17
<h3>How to interpret the residual plot?</h3>
The figure (1) represents the residual plot.
In the residual plot of a linear model, the line of the plot is represented by a horizontal line
From the figure, the line of the plot is not an horizontal line.
Hence, the residual plot does not show a linear model
<h3>The estimated GPA</h3>
The number of hours is given as:
x = 15 hours
The regression line is given as:
y = 0.134x + 1.16
Substitute 15 for x
y = 0.134 * 15 + 1.16
Evaluate
y =3.17
Hence, the estimated GPA of a student who studies for 15 hours a week is 3.17
