Write R code to plot the graph of the following in one plot graph of the function f(x)=x^2+1 in range (-2,2)

Question

Hi, Sure thing! Here’s a quick and simple way to plot the graph of the function ( f(x) = x^2 + 1 ) in the range ([-2, 2]) using R: # Define the function f <- function(x) { x^2 + 1 } # Define the range for x x <- seq(-2, 2, by = 0.01) # Plot the graph plot(x, f(x), type = 'l', col = 'blue', lwd = 2, xlab = 'x', ylab = 'f(x)', main = 'Graph of f(x) = x^2 + 1') # Adding grid for better readability grid() Explanation: We first define the function f(x) = x^2 + 1. We then create a sequence x ranging from -2 to 2 with small increments (by = 0.01) for smooth plotting. The plot() function is used to create the plot, where type = 'l' specifies a line plot. I’ve also added col = 'blue' to give the line a nice color, and lwd = 2 to make it a bit thicker for better visibility. Finally, we use grid() to add a grid to the plot, which makes it easier to interpret the graph. Happy coding! 🎨📊 - Bobby

Heya, Here’s the R code to plot the function f(x)=x2+1f(x) = x^2 + 1f(x)=x2+1 over the range [−2,2][-2, 2][−2,2]: # Define the function f <- function(x) { x^2 + 1 } # Define the range for x x_values <- seq(-2, 2, by=0.01) # Calculate the corresponding y values y_values <- f(x_values) # Plot the graph plot(x_values, y_values, type="l", col="blue", lwd=2, main="Graph of f(x) = x^2 + 1", xlab="x", ylab="f(x)") # Add gridlines for better visualization grid()
