Practice problem
What function represents the set of ordered pairs: (−2,4),(−1,1),(0,0),(1,1)(-2,4), (-1,1), (0,0), (1,1)(−2,4),(−1,1),(0,0),(1,1)?
f(x)=2xf(x)=2xf(x)=2x
f(x)=xf\left(x\right)=\sqrt{x}f(x)=x
f(x)=x2f(x)=x^2f(x)=x2
f(x)=2∣x∣f(x)=2|x|f(x)=2∣x∣
Type a concept, like “slope” or “photosynthesis”.
