Piecewise Function with 4 eqts graphing incorrectly
For a maths assignment, I needed to create two piecewise functions in the shape of a wineglass that adhered to certain criteria.
However, one of my piecewise functions doesn't connect and I cannot figure out how to stop it from creating a voided area between two points. While I can graph the piecewise on a graphics calculator easily I cannot graph it on GeoGebra. The piecewise function contains 4 equations, of which two overlap the same area on the x-axis. It is currently this:
r_2(x) = If(x < 1.15, If(0 < x < 1.15, 4x² - 5), If(x < 7.11, If(1.15 < x < 7.11, sin(2x) - 0.5), If(x < 6, If(0 < x < 7.11, 1.5sqrt(x - 7)), If(0 < x < 19, -1.5sqrt(x - 7)))))
These are the individual eqts for each function with their correct domains
- f_2(x) = If(0 < x < 1.15, 4x² - 5)
- p_1(x) = If(1.15 < x < 7.11, sin(2x) - 0.5)
- q_2(x) = If(0 < x < 19, -1.5sqrt(x - 7))
- h_2(x) = If(0 < x < 7.11, 1.5sqrt(x - 7))
When graphed it does not connect the two SQRT eqts. to the sin eqt. Is there a way to fix this? or a way to re-write the command so that it does not "cut out" sections of the equations?
