Best ResponseYou've already chosen the best response.0y = (x+1)(x+5), I guess you can solve the rest by yourself

Best ResponseYou've already chosen the best response.0Um okay.. This is my first problem with this. And I basically have no clue as to what im doing. And what your saying doesnt follow my examples and you haven't said anything about what ive already solved.

Best ResponseYou've already chosen the best response.0It says to solve for the vertex with x=b/2a Then plug the answer for x into the problem to get the yintercept. Factor, then set each factor to 0, that gives the answer xintercept.

Best ResponseYou've already chosen the best response.0intercepts (5,0) and (1,0) for vertex put x = 3 in the equation find y y = (3+1)(3+5) = 4 so vertex (3,4)

Best ResponseYou've already chosen the best response.0Um why are you doing it with y? My examples show to do it like this f(3)= (3)^2 6(3)+5

Best ResponseYou've already chosen the best response.0y = f(x) they are both the same

Best ResponseYou've already chosen the best response.0we write it like this >> y = f(x) = (x+1)(x+5) y is a function in x
