Answer to Question #307662 in Calculus for Anniee

Question

Step by step solution on how to find the slope of the tangent line of the given function f below.

1. f(x)=2x+5

2. f(x)=x²+1

3. f(x)=x²-1

Answer 1

1. Since $f'(x)=2,$ we conclude that the slope of the tangent line of the given function at a point $x$ is equal to $2.$

2. Since $f'(x)=2x,$ we conclude that the slope of the tangent line of the given function at a point $x$ is equal to $2x.$

3. Since $f'(x)=2x,$ we conclude that the slope of the tangent line of the given function at a point $x$ is equal to $2x.$
