Find the domain of the real valued function: f(x)=x−10−−−−−√x2+9x+8=x−10−−−−−√(x+8)(x+1) Why does the x2+9x+8 become (x+8)(x+1)? Thanks for the help!

g(x)=−4x2−5x f(x)=−3x2+7x−5(g(x)) f(g(−1))=? First, let's solve for the value of the inner function, g(−1). Then we'll know what to plug into the outer function. g(−1)=−4(−1)2+(−5)(−1)I don't understand why they transformed the minus symbol into an addition symbol. This has happened a few...
