5 is the input
Step-by-step explanation:
Given
[tex]f(x) = 4x+3[/tex]
It is also given that
[tex]f(5) = 23[/tex]
When a function is given in the form of
f(a) = b
Here a is the input and b is the output on input a.
So,
We can observe from f(5) = 23, that 5 is the input and 23 is the output. We can also verify it by putting 5 in the given function
[tex]f(5) = 4(5)+3\\= 20+3\\=23[/tex]
Hence,
5 is the input
