Question
the graph of quadratic function f is given.
F(x) = -1/2x2 -2x+6
(a) Find the coordinates of the vertex and the x- and y-intercepts.
(smaller x-value)
(larger x-value)
(b) Find the maximum or minimum value of f.
The ---Select--- minimum maximum value of f is f(x) = .
(c) Find the domain and range of f. (Enter your answers using interval notation.)
please show step by step
x-intercepts (x, y) =
(smaller x-value)
(x, y) =(larger x-value)
y-intercept (x, y) =(b) Find the maximum or minimum value of f.
The ---Select--- minimum maximum value of f is f(x) = .
(c) Find the domain and range of f. (Enter your answers using interval notation.)

Explanation / Answer
Vertex = Maximum Point on the graph = (-2,8)
x intercepts = Points where the graph intersects the x axis.
= (-6,0) and (2,0)
y intercept : Point where the graph intersects the y axis. = (0,6)
Maximum occurs at vertex. So, 8.
Domain = Values on x axis where graph is present = (-infinity, infinity)
Range = Values on y axis where graph is present = (-infinity, 8)
