Answer:
circumcenter
Step-by-step explanation:
If points Q, R, S are on a circle, the sides of that triangle are chords of the circle. The point where the perpendicular bisectors of those chords meet is the center of that circumcircle. It is named the circumcenter.
Answer:
What are you talking about? I didn't understand the question.
F(x) = 3x + 1
let f(x) = y
y = 3x + 1
y - 1 = 3x
3x = y - 1
x = (y - 1)/3
From y = f(x), x = f⁻¹(y)
<span>x = (y - 1)/3
</span>
f⁻¹(y) = (y - 1)/3
f⁻¹(7) = <span>(7 - 1)/3 = 6/3 = 2
</span>f⁻¹(7)<span> = 2</span>
