Question

Determine whether the ordered pair (2. - 4) is a solution of the following equation.

y=x²
Is (2. - 4) a solution of y=x2​

Answer 1

The ordered pair (2,-4) is not a solution of the equation

Explanation:

we have the quadratic equation

`y=x^(2)`

we know that

If a ordered pair is a solution of the equation, then the ordered pair must satisfy the equation

Verify if the ordered pair (2,-4) is a solution of the quadratic equation

substitute the value of x=2, y=-4 in the equation

`-4=(2)^(2)`

`-4=4` -----> is not true

The ordered pair not satisfy the equation

therefore

The ordered pair (2,-4) is not a solution of the equation
