Answer:
the value of the function at x=-3 is y=4
Explanation:
We are given with the graph of the function
In the given graph the x value is the input and f(x) is the output
x is the input value and f(x) is the output value y
given the input value x=-3
To find the function value when x=-3 we need to find out y from the graph when x=-3
From the graph the y value is 4 when x=-3
So the value of the function at x=-3 is y=4
