Respuesta :

It only has one x intercept

Step-by-step explanation: when you graph it there is only one point where the line meets the x intercept

Use the discriminant formula.

b^2 - 4ac is the formula


(-4)^2 - 4(1)(4)

Gets 16 - 16
Equals 0

So there is one x intercept.


Note:
If the number you get is less than 0 it’s no real roots
If equals to 0 it has one real root
If more than 0, than 2 real roots
