question
find the value of f(-4).
y = f(x)
answer attempt 2 out of 2

Explanation:

Step1: Locate x = -4 on x - axis

Find the position of \( x=-4 \) on the horizontal (x - axis) of the graph.

Step2: Find corresponding y - value

From \( x = - 4\), move vertically until intersecting the graph of \( y = f(x)\). The y - coordinate at this intersection point is the value of \( f(-4)\). By observing the graph, when \( x=-4\), the point on the parabola has a y - value of 6 (since the vertex or the point at \( x = - 4\) is at \( y=6\)).

Answer:

6
