Answer:
B
Step-by-step explanation:
-2|x - 1| = -4
|x - 1| = 2
since we are dealing with a function that brings 2 values to the same result, the reverse function (needed to find the values of x that create the result y) has 2 branches :
(x - 1) = 2
and
(x - 1) = -2
x - 1 = 2
x = 3
x - 1 = -2
x = -1
therefore, B is the right answer.
3x-5=x+1
2x=6
x=3
hope this helsp

Oh well Is that it explain more
Step-by-step explanation:
Answer:
Distance is 9.21954445729 (9) and the midpoint is (-2, 1.5)
Step-by-step explanation:
Pythagorean theorem
Height = 7 and Length = 6
7^2 + 6^2 = c^2
49 + 36 = c^2
85 = c^2
c = 9.21954445729
-----------------
Botton point is (1, -2)
x: 1 - 3 = -2
y: -2 + 3.5 = 1.5
Midpoint = (-2, 1.5)
f ( - 2 ) = 5 × 3^( - 2 )
f ( - 2 ) = 5 × 1/9
f ( - 2 ) = 5/9
