Which system of equations can be graphed to find the solution(s) to x2 = 2x + 3?

A: y= x^2 + 2x +3
y= 2x + 3

B: y = x^2 -3
y= 2x + 3

C: y=x^2-2x-3
y=2x +3

D: y= x^2
y=2x+3


This question doesn't need to be answered anymore. But for those who need the answer, the answer is D: y= x^2 y=2x+3

Answer 1

Answer: The correct option is

(D)
`y=x^2\\\\y=2x+3`

Step-by-step explanation: We are given to select the correct system of equations that can be graphed to find the solution to the following quadratic equation :

`x^2=2x+3`

Let us consider another variable y such that

`y=x^2.`

Then, according to the given equation, we must have

`y=2x+3.`

Therefore, the required system of equations is

`y=x^2\\\\y=2x+3`

Thus, (D) is the correct option.
