Iwill pick the the sum of a rational number and an irrational number is always irrational. a.) false b.) true

Question

The sum of a rational number and an irrational number is always irrational.

A.) False  

B.) True

B.) True

Hope this helps!

B) true

saying that x is irrational and y is rational

x+y = z will be irrational.

Assuming that z is rational and knowing that the difference between r rationals is still a rational will imply that x is rational also. So the assumption is false and the sum is always irrational

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
