SOLUTION: What is the x- and y-intercept and the equation of the line symmetry for: {{{y=x exponent 2 + 6x +8}}}

Question 12486: What is the x- and y-intercept and the equation of the line symmetry for:

Answer by rapaljer(4671) (Show Source): You can put this solution on YOUR website!

This is a parabola, that opens upward.

The x-intercept (where y=0), is at

0= (x+2)(x+4)
x = -2, x= -4.

Y-intercept is where x=0.

Line of symmetry is always halfway between the intercepts, which would be halfway between x=-2 and x= -4. Line of symmetry is the line x= -3.
