2.1 calc difference quotient

Label the limit of the difference quotient

Label the limit of the difference quotient for f(x) = 2x² + 1

Label the limit of the difference quotient for f(x) = x³ - 3x

Label the limit of the difference quotient for f(x) = 2x - 1

Find the average rate of change of $$f\left(x\right)=-2x^2+4x+6$$  from [-3, -1].

$$f\left(x\right)=\sqrt{x+8}+2$$  
Evaluate  $$f\left(x-8\right)$$  

$$h\left(t\right)=t^2-2t$$  
Evaluate  $$h\left(x+2\right)$$  

Find the limit of the difference quotient as $$h\rightarrow0$$ for   $$f\left(x\right)=3x$$  

Find the limit of the difference quotient as $$h\rightarrow0$$ for  $$x^2-1$$   

If   $$f\left(x\right)=x^2$$  , what is the meaning of this:      $$\lim_{h\rightarrow0}\ \frac{f\left(3+h\right)-f\left(3\right)}{h}$$  ?
