Question

Can someone please help ???

Answer 1

The opening of a parabola is upwards if its two "legs" are pointing up \/ and downwards if the legs are pointing down /\
>> ( a ) upwards

The y-int is where the graph intersects with the y axis
The x-int is where the graph intersects with the x axis
>> ( b ) there is no x-int in this case
y-int = 6

The vertex is where the two "legs" meet; it's either the maximum or the minimum of the graph.
>> ( c ) v = (2 , 2)

The axis of symmetry is the line which you would consider as a "mirror" it can be either the horizontal or in this case vertical line where it is the axis of reflection.
>> ( d ) x = 2
