evaluate the function graphically. find $f(4)$
evaluate the function graphically. find $f(4)$
Answer
Explanation:
Step1: Locate x = 4 on the x - axis
We need to find the value of the function ( f(x) ) at ( x = 4 ). So, first, we identify the point on the x - axis where ( x=4 ).
Step2: Find the corresponding y - value (function value)
Looking at the graph, when ( x = 4 ), we find the point on the graph that has an x - coordinate of 4. From the graph, we can see that the point with ( x = 4 ) is a filled dot (indicating the function is defined there) and the y - coordinate of that point is - 3. So, ( f(4)=-3 ).
Answer:
( f(4)=-3 )
