Which function is the inverse of f(x) = 2x + 3? f-1 (x)=-1/2x-3/2
f-1 (x)=1/2x-3/2
f-1 (x)=-2x+3
f-1 (x)=2x+3

Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=2x+6 f - 1 ( x ) = 2 x + 6 is the inverse of f(x)=12x−3 f ( x ) = 1 2 x - 3 .

Step-by-step explanation:

The function:f(x)2x+3

Put "y" for "f(x)":y2x+3

Subtract 3 from both sides:y-32x

Divide both sides by 2:(y-3)/2x

Swap sides:x(y-3)/2

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
