The coordinates of the vertex of the function is
(-5, -28).
It is given that the function
It is required to find the coordinates of the vertex.
It is defined as the graph of a quadratic function that has something bowl-shaped.
We have a function:
This function represents a parabola.
We know the standard form of parabola in quadratic style:
By comparing the given function to the standard form of parabola, we get
a = 1, b = 10, and c = -3
The vertex of the parabola is given by:
Putting the values in the above equation, we get:
x = -5 put this value in the given parabola function, we get:
or y = -28
The coordintes = (x, y) : (-5 , -28) which is shown in the graph.
Thus, the coordinates of the vertex of the function is (-5, -28).

The equation of the line joining the points (-1,-1), (1,-1) is
y +1 =0
<u><em>Step(i):</em></u>-
Given curve y = 2 x² -3 , x = -1 and x=1
substitute x =-1 in given curve y = 2 x² -3
y = 2 (-1 )² - 3
y = 2 -3
y = - 1
First point A( -1 ,-1)
substitute x =1 in given curve y = 2 x² -3
y = 2 (1)² - 3
y = -1
Second point B( 1 , -1 )
<u><em>Step(ii):-</em></u>
A( -1, -1 ) and B( 1,-1)
slope of the line
The equation of the straight line passing through the point ( -1,-1 ) having slope m =0
y - y₁ = m ( x - x₁ )
y - (-1) = 0( x-(-1)
The equation of the line joining the points (-1,-1), (1,-1) is y +1 =0
