Best ResponseYou've already chosen the best response.2to find the y coordinate you need to put x =3 in the equation and solve for the value of y.

Best ResponseYou've already chosen the best response.2for x intercepts you need to put x^2+6x+5 = 0 and find all possible x's.

Best ResponseYou've already chosen the best response.1Okay so I have to factor x^2+6x+5=0

Best ResponseYou've already chosen the best response.2yes! (x+1)(x+5) =0; x=1,5 and f(x)'s at these x's are 0.
