Answer
$f'(x) = 5.2$
Work Step by Step
We can use the power rule to differentiate 5.2x. x is to the power of 1, so we multiply 5.2 by 1 and subtract one from the exponent of x, which results in 0 and anything to the 0th power is 1. 5.2 multiplied by 1 is 5.2. 2.3 is a constant, so its derivative is 0.
$f'(x) = 5.2 + 0 = 5.2.$
