maximum value at y = 4
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
y = - 3(x + 1)² + 4 is in this form
with vertex = (- 1, 4) and a = - 3
• If a > 0 then vertex is a minimum
• If a < 0 then vertex is a maximum
here a < 0
(- 1, 4 ) is a maximum and maximum value = 4
