the function f(x) is shown on the graph. if f(x)=0, what is x? 0 only -6 only -6, -2, 1, or 3 only -2, 1, or 3 only
Answer
Explanation:
Step1: Recall function - zero concept
The values of (x) for which (f(x)=0) are the (x) - intercepts of the graph of the function (y = f(x)).
Step2: Identify (x) - intercepts
By looking at the graph, the curve (y = f(x)) intersects the (x) - axis (where (y=f(x)=0)) at (x=-2), (x = 1), and (x = 3).
Answer:
E. (-2,1,\text{ or }3\text{ only})
