1.what is the intersection of all the open intervals containing the closed interval [0,1]? justify your answer.

2. what is the intersection of all the closed intervals containing the open interval (0,1)? justify your answer.

Step-by-step explanation:

1)

We can find an open interval . Which contains the closed interval when

Therefore, the intersection of all the open intervals containing

2)

We can find closed intervals containing in when

Since is closed, the intersection of all those intervals containing

answer: answer

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
