What is the inverse of the function f(x)= x + 3?

f^-1(x) = x-3

Step-by-step explanation:

f(x) = x+3

y=x+3

x=y+3

x-3=y

f^-1(x) = x-3

too easy lol XD

( ͡° ͜ʖ ͡° ) copy and   paste it

step-by-step explanation:

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
