Hello!
The most logical equation would be b)
Hope it helps, have a nice day!
Nooooo way mannnnn whatttttttttttttt
Trinomial 2x² + 4x + 4.
It's of the form ax²+bx+c and it's discriminant is Δ=b² - 4.a.c
(in our case Δ = 4² - (4)(2)(4) → Δ = - 32
We know that: x' = -1 + i and x" = -1 - i
If Δ > 0 we have 2 rational solutions x' and x"
If Δ = 0 we have1 rational solution x' = x"
If Δ < 0 we have 2 complex solutions x' and x", that are conjugate
In our example we have Δ = - 16 then <0 so we have 2 complex solutions
That are x'= [-b+√Δ]/2.a and x" = [-b-√Δ]/2.a
x' =

Answer:
Vertical asymptote at x=4
Step-by-step explanation:
y = (2x+3)/(x-4)
This function has a vertical asymptote where the denominator goes to zero
x-4 =0
x =4
