Answer with explanation:
⇒⇒⇒ Information about the given Parabola
Y - Intercept =4
it means parabola cuts the y axis at (0,4).
Axis of Symmetry, is x= -2.
It means line , x= -2, divides the parabola into two equal halves.
It also says that, the x coordinate of vertex is equal to , -2.
Option D: Represents the described Parabola.

Step-by-step explanation:
As
- The graph of the function passes through the point (2,1), and
- y increases by 4 when x increases by 1.
so
x y
2 1
3 5
4 9
5 13
6 17
and so on
From the table:
As the slope-intercept form of the line is
putting m=4 and any point, let say (2, 1) to find y-intercept 'b'.
So putting and
in the slope-intercept form of the line
Therefore, the equation for the linear function will be:
