Question

A function is shown f=(x)=x^2+ 2X-3

show the X intercepts and maximum or minimum of the function

Answer 1

x intercepts at (-3,0), and (1,0)

there is a minimum at (-1,-4)

Explanation:

Please see attached image for the requested graph of the function
`f(x) = x^2+2x-3`, and observe that the crossings of the x-axis are at the points (-3,0), and (1,0) , marked in red in the image.

We can also see that there is no maximum, but a minimum value, and located at the point (-1,-4) [marked in green in the image]
