f(x)=x2+1f(x) =x^2+1

we start by finding the derivative of the function f(x)by applying the sum rule.

d/dx(f(x))=d/dx(x2)+d/dx(1)d/dx(f(x))=d/dx(x^2)+d/dx(1)

=2xx

The equation for the slope of the tangent line will be the derivative of f(x)

which is 2x2x.

the equation of the line is given by the following equation

y=mx+cy=mx+c

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.
