Vertex represents a maximum or minimum point for the function. Explain your
1 answer:
Answer:
the vertex represents a maximum
Vertex is (4,7)
f(x)=-(x-4)^2+7
Step-by-step explanation:
Given the function
Equation is in the form of y=ax^2+bx+c
When 'a' is negative, then vertex is maximum
when 'a' is positive, then vertex is minimum
is negative, so the vertex represents a maximum
