#contoh memplot fungsi garis lurus:
slice_plot(3 * x + 2 ~ x, domain(x = range(0, 100)))

library(mosaicCalc)
A = 3
slice_plot( A * x ^ 2 ~ x,  domain(x = range(0, 10)),  color="red" )

slice_plot( cos(t) ~ t, domain(t = range(0,2*pi) ))

#Anda dapat menggunakan makeFun( )untuk memberi nama pada fungsi. Contohnya:
g  <- makeFun(3*x^2 + 5*x + 2 ~ x)
slice_plot(g(x) ~ x , domain(x = range(-2, 2)))

#membuat ekspresi baru dari fungsi
library(mosaicCalc)
slice_plot(sqrt(abs(g(x))) ~ x, domain(x = range(-5,10)))
