Answer
$y=\frac{3}{4}\ sin(2\pi x)$
Work Step by Step
Step 1. As the curve is odd and increases while passing $(0,0)$, we can write a general form $y=A\ sin(kx)$
Step 2. We can identify the amplitude $A=\frac{3}{4}$.
Step 3. We can identify the period $p=1$, thus $\frac{2\pi}{k}=1$ and $k=2\pi$
Step 4. The equation is $y=\frac{3}{4}\ sin(2\pi x)$
