Answer:
Step-by-step explanation:
a) We want to check if the parabola opens upwards or downwards
From the image given, we can see that the parabola open downwards
b) The axis of symmetry equation is an equation in terms of x at the point that splits the parabola into 2
We have that as the equation of the line (vertical) that splits the parabola into two parts
We have that as:
c) The coordinates of the vertex simply refer to the coordinates of the point at which the axis of symmetry line strikes the parabola
Mathematically, we have that as:
d) For the x-intercept, we refer to the points at which the curve crosses or touches the x-axis
We have these points as:
For the y-intercept, we have the touching, crossing in respect to the y-axis
We have this as:
