Step 1: Write out the equation and the given values.


\begin{gathered} h(x)=-16x^2_{}+20x+35 \\ \text{where} \\ h(x)\text{ is the height in f}eet\text{ above the river x seconds from the start} \\ x\text{ is the time in seconds} \end{gathered}

Before the diver jumps from the cliff,


x=0s

Step 2: Substitute the given value into the equation.


h(0)=-16(0)^2+20(0)+35=0+0+35=35\text{ ft}

Therefore, the diver is 35 feet above the water before he jumps from the cliff
