Part A

we have a vertical parabola open downward

Part B

Find out the y-intercept (value of y when the value of x=0)

looking at the graph

For x=0

the value of y=-4

therefore

the y-intercept is (0,-4)

Find out the x-intercepts (values of x when the value of y=0)

looking at the graph

For y=0

the value of x=2

therefore

the x-intercept is (2,0)

Part c

The equation of the axis of symmetry is equal to the x-coordinate of the vertex

The vertex is (2,0)

therefore

the axis of symmetry is x=2

Part d

the vertex is (2,0)
