To find the derivative of the function y=8x613x2, we can apply the power rule of differentiation. The power rule states that if we have a term of the form axn, the derivative with respect to x is given by d/dx(axn)=anxn1.
Let's differentiate the given function with respect to x:
dydx=ddx(8x613x2)
Applying the power rule to each term, we get:
dydx=6·8x612·13x21
Simplifying:
dydx=48x526x
Now, to find the derivative when x=2, we substitute x=2 into the derivative expression:
dydx|x=2=48(2)526(2)
Evaluating the expression:
dydx|x=2=48(32)(52)
dydx|x=2=1536+52
dydx|x=2=1484
Therefore, the derivative of the function y=8x613x2 when x=2 is 1484.
