1.-How do you calculate the slope of a curve?
R= I calculate the derivative of the function.

f(x)=x¬2

df/dx=2x¬2-1=2x

f´´(x=1)=2*1=2

• What is the slope at the origin?

R=the slope at the origin is zero.

 f´(x=1)=2*0=0

• What was the class about?

R=The class was about the derivative

• What was the name of the lesson?

R=The name of the lesson was "Rate of change"

2.-Calculate the area below the tangent line of the hyperbola?

A=2 for any point in the hyperbola

3.-What is the formula for the area?

A=1/2 b*h
