Question

The function f(x) is graphed below.

Use the graph of the function to find, f(1).

-2
-1
1
2

Answer 1

f(1) = 2

Explanation:

Answer 2

f(1) = 2

Explanation:

Since y is a function of x, that is;

y = f(x)

f(1) implies the value of y when x = 1.

To obtain this value we draw the vertical line x = 1 and check where the line intersects the graph of f(x).

In this case, the line x = 1 will intersect with the graph of f(x) on the line y = 2. The function f(x) assumes the value 2 between x = 0 and x = 4. Therefore,

f(1) = 2
