From the given graph of the quadratic function, let's find f(4).
To find f(4), we are to find the value of y when x = 4.
• The x-values are represented on the horizontal axis(x-axis).
,
• The y-values are represented on the vertical axis(y-axis).
Using the graph, when x = 4, y = 1.
Therefore, we have:
f(4) = 1
ANSWER:
f(4) = 1
