## Loading required package: mosaic

## Registered S3 method overwritten by 'mosaic':
##   method                           from   
##   fortify.SpatialPolygonsDataFrame ggplot2

## 
## The 'mosaic' package masks several functions from core packages in order to add 
## additional features.  The original behavior of these functions should not be affected by this.

## Attaching package: 'mosaic'

## The following objects are masked from 'package:dplyr':
## 
##     count, do, tally

## The following object is masked from 'package:Matrix':
## 
##     mean

## The following object is masked from 'package:ggplot2':
## 
##     stat

## The following objects are masked from 'package:stats':
## 
##     binom.test, cor, cor.test, cov, fivenum, IQR, median, prop.test,
##     quantile, sd, t.test, var

## The following objects are masked from 'package:base':
## 
##     max, mean, min, prod, range, sample, sum

## Loading required package: mosaicCore

## Attaching package: 'mosaicCore'

## The following objects are masked from 'package:dplyr':
## 
##     count, tally

## The legacy packages maptools, rgdal, and rgeos, underpinning the sp package,
## which was just loaded, will retire in October 2023.
## Please refer to R-spatial evolution reports for details, especially
## https://r-spatial.org/r/2023/05/15/evolution4.html.
## It may be desirable to make the sf package available;
## package maintainers should consider adding sf to Suggests:.
## The sp package is now running under evolution status 2
##      (status 2 uses the sf package in place of rgdal)

Graphical Zero Finding adalah cara mencari nol atau akar suatu fungsi dengan memvisualisasikannya dalam format grafik. Akar atau akar suatu fungsi adalah nilai x, f(x)=0 Untuk menggunakan cara ini, Anda perlu membuat grafik fungsi yang ingin dicari akarnya. Setelah Anda membuat grafik fungsi, Anda dapat melihat titik perpotongan kurva fungsi atau menyentuh sumbu x. Titik potong atau kontak ini merupakan akar atau nol dari fungsi .

f <- function(x) {-3*x^2 + x^5}

x <- seq(-2, 2, by = 0.01)
y <- f(x)

ggplot(data.frame(x, y), aes(x = x, y = y)) +
  geom_line() +
  geom_hline(yintercept = 0, color="deeppink") +
  ggtitle("Graphical Zero-Finding") +
  xlab("x") + ylab("f(x)")
