welding a piecewise function together at a point?
Hi I have these two functions f(x) and g(x).
f(x) = If(-4 < x < 2, 1 / 2 x + 5)
g(x) =If(2 ≤ x, x² - 7x + 16)
They graphically touch each other x = 2, but I can only get the program to acknowledge this if I change f(x) = If(-4 <= x <= 2, 1 / 2 x + 5)
Any way (scriptwise) to force Geogebra to recognize that the functions do touch at the original condition for f eventhough f(x) = If(-4 < x < 2, 1 / 2 x + 5)??
