Question

destinyyyy · Answer

f(x)+x^2+6x+5

destinyyyy · Answer

a=1 b=6 c=5

=-(6)/2(1)

princeharryyy · Answer

y = (x+1)(x+5), I guess you can solve the rest by yourself

??

princeharryyy · Answer

f(x)+x^2+6x+5 can be expressed as y = (x+1)(x+5)

destinyyyy · Answer

Um 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.

destinyyyy · Answer

It says to solve for the vertex with x=-b/2a
Then plug the answer for x into the problem to get the y-intercept.
Factor, then set each factor to 0, that gives the answer x-intercept.

it's a point where you get the maxima or minima
