that is from 55 to 145
acute means angle is less than 90 degrees
right means equal to 90
obtuse means greater than 90
so
55 to 145
145-55=90
it is right angle
It's an upside (-) down parabola. The axis of symmetry is the x coordinate of the vertex.
you can easily find this using formula: x= -b/2a
for parabola: ax² + b + c = 0
x = -16 ÷ 2(-4)
x = 2
