the graph of $y = f(x)$ is shown below. find all values of $x$ where $f(x) = 0$.
the graph of $y = f(x)$ is shown below. find all values of $x$ where $f(x) = 0$.
Answer
Explanation:
Step1: Recall the definition of roots
The values of ( x ) where ( f(x) = 0 ) are the ( x )-intercepts of the graph of ( y = f(x) ), i.e., the points where the graph crosses or touches the ( x )-axis (( y = 0 )).
Step2: Identify the x-intercept
Looking at the graph, we observe that the line ( y = f(x) ) intersects the ( x )-axis at ( x = -9 ) (since the point of intersection with the ( x )-axis has an ( x )-coordinate of -9 and ( y )-coordinate of 0).
Answer:
( x = -9 )
