Answer:
see explanation
Step-by-step explanation:
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
• If a > 0 then the vertex is a minimum
• If a < 0 then the vertex is a maximum
f(x) = (x + 1)² - 2 → has a > 0
vertex = (- 1, - 2 ) and is a minimum
g(x) = - (x - 2)² + 1 → has a < 0
vertex = (2, 1 ) and is a maximum
