# What are the solutions of the equation 2x^{2} = 2? Use a graph of the related function.

A function means a correspondence from one value x of the first set to another value y of the second set.

## Answer: x = -1 or x = 1

Let's look at the explanation to understand it better.

**Explanation:**

2x^{2} = 2 is the equation we've been given.

Let's start by dividing both sides of our equation by 2.

⇒ 2x^{2 }/ 2 = 2 / 2

⇒ x^{2} = 1

Using the square root of both sides of our equation, we get

⇒ |x| = 1

⇒ x = ±1

x = -1 or x = 1
