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

b

step-by-step explanation:

if a was wrong then it has to be b it cant be c either because not all the y intercepts are the same!

ok now , i would like brainlest plz

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
