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

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to
