Question

can you solve this question ?
given :
f(x) = 3x³ + 2x² - 5x + 6
f(x) is derivative ( f'(x) ) , so what is f'(2) ?
==========================
​

Answer 1

Answer:

f'(2) = 3.2^3 + 2.2^2 - 5.2 + 6

= 3.8 + 2.4 - 10 + 6

= 24 + 8 - 10 + 6

= 38 - 10

= 28

hope it helps

Answer 2

Answer:

39

Step-by-step explanation:

f(x) = 3x³+2x²-5x+6

=> f'(x) = d/dx( 3x³+2x²-5x+6)

= 9x²+4x-5

=> f'(2) = 9(2)²+4(2)-5

= 9×4+4×2-5

= 36+8-5

= 44-5

= 39

hope this helps you
