Using the graph as your guide, complete the following statement. the discriminant of the function is

Option C. positive

Step-by-step explanation:

we know that

If the discriminant of a quadratic function is positive, then the quadratic function has two real solutions

If the discriminant of a quadratic function is zero, then the quadratic function has one real solution

If the discriminant of a quadratic function is negative, then the quadratic function has two complex solutions

In this problem

The quadratic function has two real solutions (x-intercepts)

therefore

The discriminant is positive

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490
