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

n(x) = 1/3 x + 3
16x) = 5x-3
h(x) = x - 3
h(x) = x + 3

I think the answer would be H(x)=x-3

Answer:

h(x) = x - 3

Explanation:

To find the inverse of a function, you can switch the x and y variables.

In f(x) = x + 3, the y variables is "f(x)".

y = x + 3

Now switch the x and y.

x = y + 3

Isolate for y and replace with h(x).

x - 3 = y

y = x - 3

h(x) = x - 3
