9. For the function f (x) = (3x + 2)(2x2 - 1):
a. Find the derivative using the Product Rule.
b. Expand and simplify the function; then use the Sum and Difference Rule to find the derivative.
c. What do you conclude from the results in parts (a) and (b)?
Hey,
First I'd like to apologize to Subhotosh Khan and stapel - I unfortunately got your messages late and realized I asked my question without providing the original maths problem. Therefore I am providing it again. I have worked out most of this(if it's correct) so don't worry.
So question a is asking for the derivative which is 18x2+8x−3
so question b is asking me to EXPAND and SIMPLIFY the FUNCTION--the original function that is. The answer to this is 6x3−3x+4x2...then it asks to use the sum rule to find the derivative. This equals 18x^2−3+8x which equals back to the derivative
And question c is asking what I can really conclude about this. Nothing really pops up in my brain for this. Could you guys guide me on the right track?
