answer::::::::::::::::::::
Basically
Answer:
145
Step-by-step explanation:
The discriminant of quadratic ...
ax^2 +bx +c = 0
is ...
d = b^2 -4ac
For your quadratic, you have a=4, b=-7, c=-6, so the discriminant is ...
d = (-7)^2 -4(4)(-6) = 49 +96 = 145
The discriminant is 145.

<h3>What is the domain of the relation</h3>
R = {(-2, 4), (1, 3), (0, -4), (3, 2)}?
- A. (-2, 0, 1, 3}
- C. {0, 1, 2,4}
- B.{-4, -2, 2, 3}
- D. {-4,2,3,4}
<h2>Answer:-</h2>
Domain of relation is (-2, 1,0,3}
so option 1st is correct
