Part A
Given f(x) defined below:

The y-intercept is the value of y when x=0.

Vertex
Since the axis of symmetry is given as x=2:

Minimum/Maximum Value
Since the coefficient of x² is negative, there is a maximum value.
• Maximum Value = 9
,
• The graph opens downwards.
Part B
Given g(x) defined below:

The axis of symmetry is derived using the formula below:

• Axis of Symmetry: x=-1
,
• Vertex: (-1,-7)
