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

Step-by-step explanation:

The given function is

To find the inverse of this function, we have to replace for , and then isolate , as follows

Then, we have to switch variables, as follows

Therefore, the inverse of the given function is

The graph attached shows both functions. The blue line is the inverse of

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
