Answer: The inverse of the linear function f(x)=2x+1 is f^(-1) (x) = (1/2)x-1/2
Solution
f(x)=2x+1
y=f(x)
y=2x+1
Isolating x: Subtracting 1 both sides of the equation:
y-1=2x+1-1
y-1=2x
Multiplying both sides of the equation by 1/2:
(1/2)(y-1)=(1/2)2x
(1/2)y-1/2=x
x=(1/2)y-1/2
Changing "x" by "f^(-1) (x)" and "y" by "x":
f^(-1) (x) = (1/2)x-1/2
I believe the answer is C.
Answer:
i cant see the picture
Step-by-step explanation:
Answer:
A. 52%
B 104/200
C 0.52%
Explanation:
200 - 96 = 104
104/200 = 52% = 0.52
The radius of the circle = 0-(-4) = 4 ( because it is tangent to the x axis and the center is at (-2,-4).)
a.) equation is (x + 2)^2 + (y + 4)^2 = 16
b) table of points
x y
-4 2
- 3 -0.13
-2 0
0 -0.54
and do the same for x = 1,2 and 3
