Practice problem
What common non-linear function does the following set of ordered pairs represent?
(1,1),(4,2),(9,3),(16,4)(1,1), (4,2), (9,3), (16,4)(1,1),(4,2),(9,3),(16,4)
f(x)=12xf\left(x\right)=\frac{1}{2}xf(x)=21x
f(x)=x−2f(x)=x-2f(x)=x−2
f(x)=xf\left(x\right)=\sqrt{x}f(x)=x
f(x)=x2f(x)=x^2f(x)=x2
Type a concept, like “slope” or “photosynthesis”.
