How we can write quadratic equation (Mathematical functions) In Julia

Suppose i wanted to write a fun y = x^2+1

and wanted to plot in scatter. So how can i plot this in Julia?

i tried this method but didn’t work

y(x) = x^2+1
x = 1:10

Try scatter(x,y.(x)) dots after function names (.) make functions broadcast (be applied element-wise)


In this case (using Plots)

f(x) = x^2 + 1
scatter(f, x)

should also work.

I understand you wanted to do a scatter plot, but if you just want to plot a function using Plots, plot(x->x^2 + 1) works as well. I’ve been told that this will work in Makie soon.
