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

h(x)=1/3x + 3
h(x)=1/3x - 3
h(x)= x - 3
h(x)= x + 3


Sagot :

Step-by-step explanation:

the inverse function simply calculate the original x it of a given y. so, we need to transform the original function to calculate x instead of y.

and then, at the end to make it a formally correct function definition, we rename x to y and y to x.

y = x + 3

x = y - 3

=> to make it a formally correct function definition

y = x - 3 = h(x)
