Can someone me with these questions?

1) identify the domain of the graph y= - 6x – 13
a) all real numbers
b) x < _ - 4
c) x > _ - 6
d) x > _ - 2

2) determine which of the following statements is true concerning the values described in column #1 and column #2
column 1: the x coordinate of the vertex of the graph of y= – 2x^2 – 4x + 12
column 2: the x coordinate of the vertex of the graph of y = x^2 - 4x + 3
a) the value found in column #1 is greater then the value found in column #2
b) the value found in column #1 is less than the value found in column #2
c) the value found in column #1 is equivalent to the value found in column #2
d) the value found between column #1 and column #2 cannot be determined by the information given

3) a football is kicked toward the goal. the height of the ball is modeled by the function h(t)= —16t^2 + 64t where t equals the time in seconds and h(t) represents the height of the ball at time t seconds. what is the axis of symmetry and what does it represent?
a) t=2; it takes 2 seconds to reach maximum height and 2 seconds to fall back to the ground
b) t=2 ; it takes 2 seconds to reach maximum height and 4 seconds to fall back to the ground
c) t=4 it takes 4 seconds to reach maximum height and 4 seconds to fall back to the ground
d) it takes 4 seconds to reach maximum height and 8 seconds to fall back to the ground

4) choose the equation below whose axis of symmetry is x = 0

a) y= x^2 + 2x
b) y = x^2 – 16x + 58
c) y= x^2 + 2
d) y = x^2 – 4x + 2
