A graph of a quadratic function is shown below.
graph of y equals negative 2 times x squared plus 40 x plus 600
Which of the following equations represents the axis of symmetry for the parabola shown?
y = 10x
x = 10
x = y + 10
y = x + 10

Best ResponseYou've already chosen the best response.1y equals negative 2 times x squared plus 40 x plus 600 y=2*x^2+40x+600 =2(x^220x300) =2( (x30)(x+10) ) the roots are x=30 and x=10 the mid point is at (30+10)/2 = 10

Best ResponseYou've already chosen the best response.1that is the line x=10 because if u look at the coordinates along that vertical line, all its x coordinates of its points have 10 in it
