<span>f(x)=(<span><span>3x−1)/</span>2<----Starter </span></span>
y = (3x-1)/2
switch x and y
x = (3y-1)/2
2x = 3y-1
2x+1 =3y
y = 2/3*x + 1/3
f^(-1) (x) = 2/3*x + 1/3
f^(-1) (4) = 2/3*4 + 1/3 = 8/3 + 1/3 = 9/3 = 3
I hope this helps. ;)
Answer: -5
First, coordinates are (x, y). You’re x is 3, so all you need to do it plug in x into your algebraic equation to find y. Then just plug both into (x, y) and you have your coordinates.
y=-2(3)+1
y=-6+1
y=-5
First you wanna distribute the 3 to x and 4
So the problem will then be 3x+12= 27
Then you wanna subtract 12 from 27
You get 3x = 15
Now you wanna divide 3x and 15 by 3
You then get X = 5
