How do you know if a graph is a function of x
How do you know if a graph is a function of x-In general, a linear function is a function that can be written in the form f(x) = mx bLinear Function where the slope m and b represent any real numbers Because y = f(x), we can use y and f(x) interchangeably, and ordered pair solutions on the graph (x, y) can be written in the form (x, f(x)) (x, y) ⇔ (x, f(x))There are three basic methods of graphing linear functions The first is by plotting points and then drawing a line through the points The second is by using the y intercept and slope The third is applying transformations to the identity function f (x) = x f ( x) = x
