evaluating a quadratic function using a graph. the graph of f(x) is shown. estimate f(-3). f(-3) =
Answer
Explanation:
Step1: Locate x - value on graph
Locate $x=-3$ on the x - axis.
Step2: Find corresponding y - value
Find the y - value of the point on the graph with $x = - 3$. Looking at the graph, when $x=-3$, the y - value of the function $y = f(x)$ is 12.
Answer:
12
