Question

X-Intercepts?
Y- intercepts?
Vertex?
Equation of the axis of symmetry:
If this graph showed the standard form of the equation, would the “a” value be a positive or a negative number?

Answer 1

Answer:

x-ints:  (2,0) & (4,0)

y-int:  (0,-8)

vertex: (3,1)  *highest point of the graph

line of symmetry: x = 3  *x-value in the middle of x-ints

a value is -#  *if parabola points done it's negative, if it points up it's positive
