Question

20POINTS!

The table shows a f(x).

Find f(3)

X f(x)
1 -4
2 5
3 1
4 0
5 8

Answer 1

This problem is quite simple, I'll try to help you understand why it is~

f(x) is NOT f times x, but it is f, the function of x.

This means that the value of f depends on the value of x. f(1) means the value of the function, f, when x = 1.

Thus, f(3) is the value of the function, f(x), when x = 3. According to the table, f(x) is 1 when x is 3. That should be your answer.

Please do let me know if you still do not understand.

Happy Studying~
