tab <- mtcars[1:10, ]
boxdat <- scale(1:30)

Question

What is the derivative of $f(x) = x^{r 1} e^{r 2 x}$, evaluated at $x = r 4$? A formula is $$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}.$$

Here comes a table

knitr::kable(tab)

Here comes some R output:

t.test(1:10)

Some R code:

dat <- 1:20
s <- 0
for (i in seq_along(dat)) {
  s <- s + dat[i]
}

Here's a boxplot

boxplot(boxdat, main = "Beauty")
