Find the slope of the tangent line of the given function f below.
f(x)=x²+1
we start by finding the derivative of the function f(x)by applying the sum rule.
=2
The equation for the slope of the tangent line will be the derivative of f(x)
which is .
the equation of the line is given by the following equation
where m is the slope of the tangent and c is a constant.
y=2x
therefore the slope of this equation is 2.
The slope of the tangent line for the given equation is 2.
