Question

Помогите!!!!!При каком значении аргумента х значение функции у=0,5х2 равно 2?

Answer 1

Y=0,5x²    y=2
х=?

0,5x²=2
x²=2:0,5
x²=4
x₁=√4  и   x₂=-√4
x₁=2         x₂=-2
Ответ: -2 и 2

Answer 2

Finding the Value of x When y = 0.5x^2 Equals 2

To find the value of x when the function y = 0.5x^2 equals 2, we can set up the equation and solve for x.

The equation is: 0.5x^2 = 2

To solve for x, we can use the following steps:

1. Multiply both sides of the equation by 2 to get rid of the fraction: x^2 = 4

2. Take the square root of both sides to solve for x: x = ±2

So, the value of x when y = 0.5x^2 equals 2 is x = ±2.
