What is the sum of the geometric series?

Essentially this is asking you to sum the first three values of the geometric series that starts with i being 1 and has the rule of ().

Since we must sum the first three geometric values we need to see what the value of i will be for the first three. The sigma notation shows us that the first i will be equal to 1. This means the second i is 2 and the third i is 3.

Knowing this you can plug in the corresponding i values into () and sum it all together

() + () + ()

() + () + ()

() + () + ()

(8) + (2) + ()

10 +

10.5

Hope this helped!

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
