The coordinates of the vertex of the function \rm f(x) = x^2+10x-3  is

(-5, -28).

It is given that the function  \rm f(x) = x^2+10x-3

It is required to find the coordinates of the vertex.

<h3>What is a parabola?</h3>

It is defined as the graph of a quadratic function that has something bowl-shaped.

We have a function:

\rm f(x) = x^2+10x-3

This function represents a parabola.

We know the standard form of parabola in quadratic style:

\rm f(x)=ax^2+bx+c

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:

\rm x = -\frac{b}{2a}

Putting the values in the above equation, we get:

\rm x = -\frac{10}{2\times1} \Rightarrow -5

x = -5 put this value in the given parabola function, we get:

\rm f(-5) = (-5)^2+10(-5)-3\\\rm f(-5) = 25-50-3\\\rm f(-5) = -28

or y = -28

The coordintes = (x, y) : (-5 , -28) which is shown in the graph.

Thus, the coordinates of the vertex of the function \rm f(x) = x^2+10x-3  is (-5, -28).
