Answer:
4
Step-by-step explanation:
Written in standard form, the quadratic is ...
x^2 -2x -3 = 0
This can be factored as ...
(x -3)(x +1) = 0
so the solutions are ...
x = 3, x = -1 . . . . . . values of x that make the factors zero
The difference of interest is ...
3 -(-1) = 4
Y= 19.25x / which is the 3rd one
I'm pretty sure that the answer is A., because if you turn the fraction into a decimal and multiply it by 24, you get 7.999992, which estimates to be 8.
