Answer:
B. 5x^4 - 28x^2 + 25x - 6
Step-by-step explanation:
the steps r in the pic above
Y + 9 = 3(x + 9)
Distribute on the the right side.
y + 9 = 3x + 27
Subtract y from both sides.
9 = 3x - y + 27
Subtract 27 from both sides.
-18 = 3x - y
Switch sides.
3x - y = -18
Y = x2 - 18x
We look for the inverse of the function.
To do this, let's determine the value of x:
y = x2 - 18x
y = (x + (-18/2)) ^ 2 - ((-18) ^ 2/4) + 0
y = (x - 9) ^ 2 - 81
y + 81 = (x - 9) ^ 2
+/- root (y + 81) = (x - 9)
+/- root (y + 81) + 9 = x
We return the change:
f (x) ^ - 1 = +/- root (x + 81) + 9
Therefore, the values sought are:
b = 1
c = 81
d = 9
Answer:
f (x) ^ - 1 = +/- root (x + 81) + 9
b = 1
c = 81
d = 9
Circumference: 2 * pi * r
2 * pi * 0.5 = 3.14159
The value is pi
