Answer:
f⁻¹(x) = 1/2 x -3/2
Step-by-step explanation:
f(x) = 2x-3 ... y = 2x -3
replace x and y: x' = 2y' -3
solve y': y' = 1/2 x' - 3/2
f⁻¹(x) = 1/2 x -3/2

Step-by-step explanation:
Answer:
distance= 9 units to the nearest
Step-by-step explanation:
using the formula
√(∆x)^2+(∆y)^2
√73
= 8.5
= 9 units
Answer: Choice A) 8
------------------------------------------------------------------
If you plot all of the points, you'll see they all fall on the same straight line. The slope of this line is m = -4
Each time x increases by 1, y decreases by 4
Going in reverse, if we decrease x by 1, then we increase y by 4
So the pair (x,y) = (1,4) shown in row 2 will lead to (0,8) if we use the trick of increasing y by 4 when decreasing x by 1.
Another way to see this is to use m = -4 with (x,y) = (1,4) and you'll find that b = 8. So the equation of this line is y = -4x+8
Or you can use a graphical method to find the y intercept
Either way, the answer is 8. This is where the graph crosses the y axis.
