Question

If y = f(x) = x3 - 5x + 3 then the value of f'(5)​

Answer 1

If y = f(x) = x3 - 5x + 3 then the value of f'(5)

$\\ \longrightarrow\sf {f( 5) = {5}^{3} - 5\times 5 + 3}$

$\\ \longrightarrow\sf {f( 5) = 125 - 25 + 3}$

$\\ \longrightarrow\sf {f( 5) = 100 + 3}$

$\\ \longrightarrow\sf {f( 5) = 103}$
