You really need to tell us more about the source of these numbers. In particular, are the decimal numbers rounded or exact?

comment For all integrable $f:[-1,1]\mapsto \mathbb{R}$ prove that $\int_{-1}^1f^2(x)\ge\frac12(\int_{-1}^1f(x))^2+\frac32(\int_{-1}^1xf(x))^2$
Please spell Cauchy-Schwarz correctly.
