Question

f(x) = x2 + 2          -------          x  + 4        I need some helpfinding the x-intercepts to this problem please. The firststep I take is                           x2+ 2 = 0 then subtract 2                           x2= -2 and its here that I get lost. f(x) = x2 + 2          -------          x  + 4        I need some helpfinding the x-intercepts to this problem please. The firststep I take is                           x2+ 2 = 0 then subtract 2                           x2= -2 and its here that I get lost.

Explanation / Answer

you set f(x)=0 then multipled (x+4) across which give youx^2+2=0. Then you realized you cannot take the square root ofa negative for this type of problem. You proved there are nox-intercepts without realizing it. Try graphing it out with acalculator and maybe you'll better understand.
