ANSWER: (5,2)
according to the graph, the vertices of the
curve are 5 in abscissa and 2 in ordinate
hence the vertex (5,2)
Answer:
4.2 or 4
Step-by-step explanation:
√18 = 4.24264068712
or 4.2
or 4
C
Step-by-step explanation:
This has a U like shape so it a parabola.
Parabola correlate with quadratic functions

Since it Going down, the answer is C -x^2.
Y = - x^2 - 2
the vertex of - x^2 will be at (0,0)
the -2 translates the graph down 2 units
The answer is the vertex is at (0,-2) and as the coefficient of x^2 is negative it is a maximum
Answer is D.
