Can someone explain how to solve this? Thank you. Find the coordinates of the vertex and the intercepts of the following quadratic function. When necessary, approximate the xintercepts to the nearest tenth.

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.0Okay... For yintercept f(0)=(0)^2+6(0)+5 5 (0,5) ?

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.0Okay 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.
