Answer:
65
Step-by-step explanation:
6+5=11
Answer:
(- 1, 2)
Step-by-step explanation:
Given a quadratic in standard form y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= - 
f(x) = x² + 2x + 3 ← is in standard form
with a = 1 and b = 2, hence
= -
= - 1
Substitute x = - 1 into f(x) for corresponding value of y
f(- 1) = (- 1)² + 2(- 1) + 3 = 1 - 2 + 3 = 2
vertex = (- 1, 2 )
Answer:
b). (0, 4)
if you need an explanation, comment, and I will put one in for you :)
Yes it is a function!, all the first numbers are none repeating, for example it says -5,4,6 since they are not the same this is a function
