9. f(x)= 1/3x-2
f(3)= 1/3(3)-2
f(3)= 1-2
f(3)= -1
If I could get more context then that would help. Because an exponent being an odd number doesn’t do anything, so it could be either a negative or a positive
f(x) = 2x + 1
y = 2x + 1
x = 2y + 1
x - 1 = 2y
2 2
¹/₂x - ¹/₂ = y
The answer is A.
Horizontal, x
straight up and down, y
if you have a 3d plane, z
Subtract 2 from both sides
then you get -y equals 1/3x -2 so you have to flip the sign of the entire equation because you can’t have a negative line
so you get y = -1/3x + 2
the y-intercept is (0,2)
the slope is -1/3x (aka -x/3)
