Question

Using the graph of f(x) determine the value of f(4)

Answer 1

Given,

The grpah of the function is given in the question.

The value of f(x) is determined by the grpah.

So, at any point of x on the curve.

The coordnate of y gives the value of function.

So, at x= 4.

The curve is at y=0.

Hence, the value of f(4) is 0.
