Find the x- and y-intercepts and the equation of the line of symmetry for the graph of y = x2 + 6x + 8. Homework Help ✎
Substitute 0 for y and solve to find the x-intercepts.
Substitute 0 for x to find the y-intercept.
Start to sketch the graph by locating the x-intercepts and use the location of the x-intercepts to figure out where the axis of symmetry must be.
The y-intercept is (0, 8), the x-intercepts are (−2, 0) and (−4, 0), and the line of symmetry is x = −3.
