The value of f(-1) is -6
A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.
Given:
f(x) = 12/ (4x +2)
for x=-1
then,
f(-1) = 12/ ( 4(-1) + 2)
f(-1) = 12/ (-4 + 2)
f(-1) = 12/(-2)
f(-1) = -12/2
f(-1) = -6
Hence, the value of f(-1) is -6

Answer:
D (-4, -9)
Step-by-step explanation:
midpoint formula:
(x₁ + x₂) / 2 , (y₁ + y₂) / 2
plug in C (2,7)
(2 + x₂) / 2 , (7 + y₂ ) / 2 = (-1, -1)
(2 + x₂) / 2 = -1
multiply each side by 2
2 + x₂ = -2
subtract 2 from both sides
x₂ = -4
(7 + y₂) / 2 = -1
multiply each side by 2
7 + y₂ = -2
subtract 7 from both sides
y₂ = -9
