Example Question #31 : Derivative At A Point
What is the slope of a function at the point
?
None of the above
Slope is defined as the first derivative of a function at given point.
We are given the function
and a point
, so we need to find the derivative
and solve for the point's
-coordinate.
Using the Power Rule
for all nonzero
, we can derive
.
Substituting the -coordinate
, we have a slope:
.
