Differentiate the function.
$ f(x) = 5.2x + 2.3 $
It's clear, son, when you reign here, so we're gonna derive 5.2 x plus 23 2.3. You separate these. So we derived them separately to get 5.2 D over T x of X, let's zero, and this is equal to 5.2 due to the power power roll which seems that access equal to X to the first power.
