Answer:
1. The solutions marked on the attached graph
2.The solutions are (-2, 0) and (6, 0)
3. The discriminant would be positive
Step-by-step explanation:
- The solution of the quadratic equation is the values of x at y = 0, which means the points of intersection of the graph and the x-axis
- The discriminant is positive if the graph intersects the x-axis at two different points
- The discriminant is zero if the graph intersects the x-axis at only one point
- The discriminant is negative if the graph does not intersect the x-axis
<em>Based on the given graph</em>
1.
Look at the attached figure to see the solutions
2.
∵ The graph intersects the x-axis at points (-2, 0), (6, 0)
∴ The solutions are (-2, 0) and (6, 0)
3.
∵ The discriminant is positive if the graph intersects the x-axis
at 2 different points
∵ The given graph intersects the x-axis at points (-2, 0) and (6, 0)
→ They are different points
∴ The discriminant would be positive

Answer:
The fractions are not in order from least to greatest.
Step-by-step explanation:
Given order of fractions from least to greatest:
To check if the fractions are in correct order.
Solution:
The fractions given have same numerators but different denominators.
For fractions the higher the denominator the lower is the value of that fraction.
Thus, in the given list the least value fraction will be the fraction with the greatest denominator which is and the greatest value fraction will be the fraction with the least denominator which is
So, the order of the fractions from least to greatest is not correct. Instead the order is from greatest to least.
The correct order from least to greatest should be:
