Find an approximation to the net signed area in the earlier problem: $($solved; Area$=20/3)$ by using Left Riemann sum over the interval between the two x $$ intercepts. Let the interval be divided into n $=7$ x $5$ x $10$ equal parts. You will be using the summation formulas covered in this chapter. It is better to express the quadratic function in the general form g $($x$)=$ ax$^2+$ bx $+$ c$.$

Extra information:

Function in general form is: g$($x$)=-5($x$-6)^2+5$

Range: $(-$infinty,$5)$ X$-$intercepts: $(7,0)(5,0)$ Vertex: $(6,5).$ Please explain so I could understand each step and how to arrive to the answer. Please assure the final answer is correct
