The first 3 are functions as their x coordinate (number on the left side of the parentheses) is not repeated in any of the other parentheses
Answer:
Option D. two complex roots
Step-by-step explanation:
we know that
In a quadratic equation of the form
the discriminant D is equal to
in this problem we have
so
substitute the values
The discriminant is negative
therefore
The quadratic equation has two complex roots

Answer:
A
Step-by-step explanation:
Given the 2 equations
y = 3x + 3 → (1)
y = - 2x + 3 → (2)
Substitute y = 3x + 3 into (2)
3x + 3 = - 2x + 3 ( add 2x to both sides )
5x + 3 = 3 ( subtract 3 from both sides )
5x = 0 , then
x = 0
Substitute x = 0 into (1)
y = 3(0) + 3 = 0 + 3 = 3
solution is (0, 3 ) → A
