Let f(x)=x^2+5x3.
Find f′(x) and find f′(1).

Calculus 
Allie,
f'= 2x+5
F'(1) is 7

Allison,
thanks allie but i need someone to show the work to how they got those answers too please :)

Calculus 
Ed,
She found the derivative of the equation, and then simply plugged in a one for the (x) after it was in its derivative form.

Calculus 
Allison,
yes I know that but I need to steps for how you find the derivative.

Calculus 
Steve,
basically just the power rule:
y = x^n
y' = n*x^(n1)
