Answer:
C
Step-by-step explanation:
y = -f(x) is the reflection about the x-axis of the graph y = f(x).
Answer:
it is the 2nd 1
Step-by-step explanation:
i know this because i do
F(x) = x² + 4
y = x² + 4
First, I reverse the equation to be
x² + 4 = y
Second, we need only x to remain on the left side and we need to move the others to the right side
x² + 4 = y
x² = y - 4
x = √(y - 4)
Last, change into invers function
f⁻¹(x) = √(x - 4)
-4 times -2 equals 8.
8 times -1 equals -8.
Therefore, the point on your number line that is on -8 is your answer!
