Question

FAN AND MEDAL !! Find the derivative of f(x)=-7x^2+5x and f(x)= 4x-8

Answer 1

see do you remember the identity that:
\[\frac{ d }{ dx } x^n = nx^{n-1}\]

by applying the same to above will leas us to the answer:

\[\frac{ d }{ dx} 7x^2 + 5x = 5 - 14x\]

and the same will apply to other EQN. too:

\[\frac{ d }{ dx }4x - 8 = 4\]
