The value of f(x) is a 4 at x = -4
and the value of f(4) = -2
Explanation:
let f(x) = y
since f(x) = 4, y = 4
we find the value of x when y is 4
We trace the x and y axis:
When y =4, x = -4
The value of f(4) means x would be replaced by 4
So we check on the graph for the value of f(4) or the value of y when x = 4
At x =4, y = -2
The value of f(x) is a 4 at x = -4
and the value of f(4) = -2
