These intercepts occur at:
x = Smaller value
x = Bigger value
Enter DNE in any unused space(s).
This parabola attains a value of ?

Solution
y-6= -(x+6)^2 is the factored form vertex at (-6,6) by making x=6=0 and y-6=0 2 x-intercepts because the vertex is above the x-axis and the parabola curves down. (x+6)^2=6 so x+6=sqrt(6) and x+6=-sqrt(6) So x=-6-sqrt(6) and x=-6+sqrt(6) the second is the larger value i don\'t know what the last question means? the maximum value is y=6 and there is no minimum
