Try another version of this question If ` f(x) = \frac ( 4 ) (x^2) `, find ` f'( 3 ) `.
Get help: Box 1: Enter your answer as a number (like 5, -3, 2.2172) or as a calculation (like 5/3, 2^3, 5+4)
To find the derivative `f′(x)` of the function ` f(x) = \frac ( 4 ) (x^2) `, you need to use the power rule for differentiation. Once the derivative is determined, substitute `x=3` to calculate the specific value ` f'( 3 ) ` .
