How to do f(x) math problems
How to do f(x) math problems-The values of x are given in the xaxis or the horizontal axis, the corresponding f(x) value is given by the vertical axis At x = 2 the graph cuts the xaxis, that is the f(x) value is 0, so f(2) = 0 f(8) is the value of the function when x = 8, it is 3 so f(8) = 3 Image transcriptionsSolve problems from Pre Algebra to Calculus stepbystep \square!
