Zero or root of the 1st degree function

It is called zero or root of the first degree polynomial function f (x) = ax + b, at 0, the real number x such that f (x) = 0. We have: f (x) = 0 ax + b = 0 Let's look at some examples: Obtaining the function zero f (x) = 2 x - 5: f (x) = 0 2 x - 5 = 0 Calculating the root of the function g (x) = 3 x + 6: g (x) = 0 3 x + 6 = 0 x = -2 Calculate the abscissa of the point at which the graph of h (x) = -2x + 10 cuts the axis of the abscissa: The point at which the graph cuts the x axis is that where h (x) = 0; then: h (x) = 0 -2 x + 10 = 0 x = 5 Next: Ascending or Descending function
