[R] polynomial regression

Hi all,

I’m new to R programming.

Can someone help me , how to plot the “y” for the following equations in “R”?

𝑦= 𝑒−5(𝑥−0.3)2+0.5 𝑒−100(𝑥−0.5)2+0.5 𝑒−100(𝑥−0.75)2

𝑦=28−𝑥+10𝑥4−5𝑥9+6𝑥11

Also, I want to extract 50 random points from the function and add
normally distributed noise to the data points to get “noisy data”,
𝑦̂.  How to achieve this?

Is there a function to fit polynomial of degree 5 to the noisy data?


Thanks,
