Answer:

See below and attachment

Explanation:

Given function:

  • y = -2(x - 3)² + 4

The graph is attached and the axis of symmetry and all the required points plotted

a) Axis of symmetry:

  • x = 3

b) It has no minimum as the leading coefficient is negative.

  • Maximum value is at vertex- the point (3, 4).
  • Maximum value is y = 4

c) and d) x - and y - intercepts already given in the question

e) Domain is all real numbers. x = ( -∞, +∞ )

Range is y = ( - ∞, 4]
