Answer:
b = -9
Step-by-step explanation:
The function is given as :

The axis of symmetry for this function is x = 3/2
It is required to find the value of b. The axis of symmetry of a parabola is a vertical line that intercepts its vertex at its horizontal coordinate. It can be given by :

Putting x = 3/2 and a = 3 we get :

So, the value of b is -9.

Answer:
Evangelina and Josh can be considered correct but this can be simplified to just 28. so if you want the simplification of this problem it would be no one but both are correct if you just want to see if they equal the same answer
Step-by-step explanation:
they are correct because they could simplify it
X ≤ 40
