Answer:
C. 0
Step-by-step explanation:
The points of intercection between the graph of a quadratic function of the form are given by the discriminant of the quadratic formula.
Remember that the quadratic formula is:
The discriminant of he quadratic formula is just the thing inside the radical, in other words:
- If the discriminant is negative, the graph of the quadratic function doesn't intercept the x-axis.
- If the discriminant is positive, the graph of the quadratic function intercept the x-axis at 2 points.
- If the discriminant is 0, the graph of the quadratic function intercept the x-axis at 1 point.
We can infer form our quadratic that , , and , so let's replace the values in the discriminant:
Since the discriminant is negative, we can conclude that the graph of the quadratic function doesn't intercept the x-axis at any point.
Answer:
the answer is 11x. just add everything together.
What is the sum of the geometric series Σ2
Σ(3)
rounded to the nearest whole number?
Answer: O2
I believe that it's no,<span> it is not a valid inference because her classmates do not make up a random sample of the students in the school. But I can't be sure, I really haven't done much on inferences, especially in math. I know for sure that her inference is incorrect though. Hope this helps, even a bit!</span>
According tome it should come 1 but thre is no option
