f(x) = (x−2)^3 

f(x) = \sqrt{-x+1}

f(x) = \dfrac{1}{x^2} 

f(x) = \dfrac{1}{x+1}

f(x) = (x+3)^2

f(x) = (x−2)^3 

f(x) = \sqrt{-x+1}

f(x) = \dfrac{1}{x+1}

f(x) = \sqrt{-x+1}

f(x) = x + x^2

f(x) = \dfrac{1}{x^2} 

f(x) = \dfrac{1}{x+1}

f(x) = (x−2)^3 

f(x) = x + x^2

f(x) = \dfrac{1}{x^2} 

f(x) = (x+3)^2

f(x) = (x−2)^3 

f(x) = x + x^2

f(x) = \dfrac{1}{x^2}
