For the function f(x) = -2(x + 3)^2 - 1, identify the vertex, domain, and range.

vertex (-3 , - 1)

domain : all real number

range: y <= -1

Step-by-step explanation:

y = a(x-h)^2 + k where vertex (h, k)

In this case

f(x) = -2(x + 3)^2 - 1 , h = - 3 and k = -1

So vertex (-3 , - 1)

Since a = - 2<0, the function is downward and  has maximum = -1

So Domain : all real number and range: y <= -1

Vertex (-3,-1)

Domain :set of real numbers

Range:=(

Step-by-step explanation:

We  are given that a function

We have to find the vertex , domain and range of given function.

We know that equation of parabola whose vertex at (h,k) is given by

Compare with the given equation then we get

Vertex=(-3,-1)

Substitute x=-3 then we get

y=-1

Domain:all real numbers because given function is defined for all real numbers.

Range=(-infinity, -1]

Therefore, domain of f(x)=R

Range=(-

£116.67

Step-by-step explanation:

Given;

Nar donated to 4 charities last year. She gave £175 to each of these charities.

The total amount Nar donated is;

Nar = 4 × £175 = £700

For Rana to donate the same amount equally among 6 charity, to determine the amount each charity would receive this year, we need to divide the total amount by the number of charities;

A = £700/6

A = £116.67
