which of the following answer choices describes all the transformation found in the cubic function f(x)=-(x+2)3-5

Alona [7]

The cubic function is f(x) = x^3

You need to perform three transformations to the cubic function to obtain
f(x) = - (x + 2)^3 - 5.

Those transfformations are:

1) Shift f(x) = x^3, 2 units leftward to obtain f(x) = (x + 2)^3

2) reflect f(x) = (x + 2)^3 across the x-axis to obtain f(x) = - (x + 2)^3

3) shift f(x) = - ( x + 2) ^3, 5 units downward to obtain f(x) = - (x + 2)^3 - 5

What is the sum of the first 1,000 consecutive odd numbers?

Leokris [45]

That is an arithmetic sequence of the form:

a(n)=2n-1

Now the sum of an arithmetic sequence is just the average of the first and last terms times the number of terms...

We know the first term is 1, let's find the last term...

a(1000)=2(1000)-1=1999

So the sum of that sequence is:

1000(1999+1)/2

1,000,000
