Which function is the inverse of f(x) = 2x + 3?​

f^-1(x)=1/2x-3/2

Step-by-step explanation:

f(x)=2x+3

y=2x+3

x=2y+3

2y+3=x

2y=x-3

y=1/2x-3/2

substitute f^-1(x) for y

f^-1(x)=1/2x-3/2

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this
