Question

Use the graph to fill in the blank with the correct number.
f(0)=________

Answer 1

f(0) = 1

Explanation:

The graph given to us shows that we have 2 values for y when x = 0. Since point (0, 0) is an open dot, it is not included in the function, meaning it is not usable. The other point, (0, 1), is a closed dot, so we can use that. Therefore, f(0) = 1.
