Identify the vertex, axis of symmetry, minimum or maximum, domain, and range of the function ()=−(+)^−

vertex = (-4, -5)

Axis of symmetry = -4

use the (-4, -5) to find the minimum value

Solution:

Given function is:

The equation in vertex form is given as:

Where, (h, k) is constant

On comparing give function with vertex form,

h = -4

k = -5

Vertex is (-4 , -5)

Axis of symmetry : x co-ordinate of vertex

Thus, axis of symmetry = -4

The coefficient of x^2 is positive in given function.

Thus the vertex point will be a minimum

On comparing,

a = 1

b = 8

Thus, use the (-4, -5) to find the minimum value

Domain and range

The domain is the input values shown on the x-axis

The range is the set of possible output values f(x)

Therefore,

i just took the test, the correct answer is .. 31.5 in.
