Question

A. If f(2)= 5, then the point __ is on the graph of f.

b. If (5,0) is on the graph of f, then f(5) =__

Answer 1

a. (2, 5)

b. 0

Explanation:

The function is y = f(x)

If we plug in a value for x, we should get a value for y and that (x, y) will be a point

a. We have x = 2 and y = f(2) = 5
So x = 2, y = 5 is a point otherwise written as (2, 5)

b. If y = 0, when x = 5 then f(5) = 0
