Question 2

2.

Match the unique rational zeros to their equations. Every option will be used one time, and one time only.

\pm 7
\pm 21
\pm 16
\pm \frac{7}{5}
\pm 3
\pm \frac{21}{5}
\pm 32
\pm \frac{4}{5}
\pm \frac{3}{5}
\pm \frac{8}{5}
\pm 64
\pm \frac{2}{5}

f(x)=x^{6}-64
f(x)=5x^{3}-2x^{2}+20x-8
f(x)=5x^{4}+32x^{2}-21
