Answer:
Step-by-step explanation:
A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2. Example. f(x)=x+7.
Answer:
3
Step-by-step explanation:
This is very simple.
f(x) means the function of x.
The question means,
"What is the function result if 2 was x"
The table does not show how it works, but it gives the result directly.
In the table, in the "x" column, there is a 2.
In the "f(x)" column, there is a 3 next to the number 2.
