- Question 11 Find the derivative of f (z) = -2 . 5%. 2 points How Did I Do? Enclose arguments of functions, numerators, and denominators in parentheses. For example, sin (2x) (a - b) / (1 + n). f (z) = -2.5^z In (2.5)Let's find the derivative stepbystep. d g ( -2 (52') ) Use the constant multiple rule. d . = g( 1252) _ z - '2 (a ( 5 ) ) 2 2(52) (1n (5) )
