Hello I am in third and I have an exercise in math on consider the function f defined on r by:f (x) = 0.5 (x + 1) ²-1.
1. construct an array of values of f for x ranging from -4 to 3 with a step of 1
2. draw in a coordinate system the curve representative of f.
take as unit 1cm on the abscissa axis and 1cm on the ordinate axis
3.Graphically solve f (x)> 2.
