Please help I need this to pass my classs

a. Maximum

b. (-1, 4)

c. -3, 1

d. x = -1

Step-by-step explanation:

a. There is a maximum value of the function (highest point) because the parabola opens downward.

b. The vertex is the turning point--the point where the maximum is.

c. The roots (or "zeros") are the values of  x  where the curve intersects the x-axis

d. The axis of symmetry is a vertical line which passes through the vertex.

what "following statement"?

step-by-step explanation:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
