Answer:
B. 1 x-intercept
Explanation:
We can use the discriminant expression, b²- 4ac, to answer this question.
In the equation y = 3x² + 6x + 3 we know that,
3 = a-value
6 = b-value
3 = c-value
Using this information, we can plug these numbers into the discriminant expression to find the discriminant.
6² - 4(3)(3) = 0
Because the value is equal to 0, we know there is 1 real solution and therefore there is 1 x-intercept.
