The required equation of graph f(x) is [tex]y = -x^{2} -3[/tex]
Given that,
The graph of f(x), resembles the graph of G(x) = [tex]x^{2}[/tex].
We have to find,
Which of the following could be the equation of f(x).
According to the question,
Function, [tex]G(x) = x^{2}[/tex],
The graph in the given question figure.
It is a parabola with vertex at (0,0).
By the graph predict that Sign of [tex]x^{2}[/tex] is positive, that is why the parabola opens up.
General equation of parabola is given by,
[tex]y = a(x-h)^{2} +k[/tex]
Where, a = 1, and vertex (h, k) is (0,0).
The graph of F(x) unknown function opens down ,
Sign of [tex]x^{2}[/tex] as negative.
and the vertex is at (0,-3)
To find the equation of function f(x),
Putting the values of a and vertex coordinates,
[tex]y = a(x-h)^{2} +k[/tex]
The equation of parabola become:
[tex]y = -1(x-0)^{2} +(-3)\\\\y = -x^{2} -3[/tex]
Hence, The required equation of f(x) is [tex]y = -x^{2} -3[/tex].
