I'm am trying to find the x and y intercept of f(x)=x(squared)-3+1 
how do I come about doing this.:confused:

The x intercept is where the function intercepts with the x axis, As the x axis is defined by the line y = 0, you can set y to 0 in your equation and then solve for x, this value of x is the x intercept.
 
Vice versa for the y intercept.

And keep in mind that f(x) = y.  It looks confusing when written as a function.  But the left side of the equal sign is essentially y.  So just use a y when doing the solving part and it'll be easier.
