Which of the functions below could have created this graph?
2 answers:
Answer:
option c, .
Step-by-step explanation:
Given : graph.
To find : which of the functions below could have created this graph.
Solution : We see from the graph both end point are below
By the End Behavior of the function : if the degree of polynomial is even and leading coefficient is negative then the both end point of graph would be below.
We can see from option c , it has degree = 4 (even) and leading coefficient is negative.
Therefore, option c, .

The quadratic equation equivalent to this expression:
Solution:
The common denominator here is 3x;
So, multiply both sides by 3x
x 3x =
3x
5 x 3 = (x + 2)x
15 = x² + 2x
So;
x² + 2x - 15
The quadratic expression is x² + 2x - 15
