Answer:
first on is 2, second is -5, third is 8, and the last one is -147
Step-by-step explanation:
The discriminant explains how many solutions the quadratic function has. It is found using this formula:

Using the formula, there are three rules. Let's say the discriminant=d:
d<0 - No solution ø
d=0 -ONLY 1 solution
d>0 -2 solutions
In the following graph, there are no solutions as the graph does not hit the x-axis at any point.
Thereafter, the discriminant MUST be less than zero. Let's view the options check which one agrees with our answer.
A - Discriminant is greater than 0, which means two solutions. This is WRONG.
B - Discriminant is less than 0, which means no solutions. CORRECT!C- Discriminant is equal to 0, which means one solution. WRONG!
Your answer is B.
If i did the math right it would be (C)
Answer:
Step-by-step explanation:
y=a(r)^{n-1}
y=1(2)^{x-1}
