I don't understand this question at all please help if you do

Answer:
Answer is [tex]\frac{4}{3}[/tex]
Step-by-step explanation:
To find the interval of x. Use our equations to equal each other.
[tex]-x^2+2x=y,y=0[/tex]
[tex]-x^2+2x=0\\-x(x-2)=0\\-x=0 , (x-2)=0\\x=0 ,2[/tex]
[tex]\int\limits^2_0 {-x^2+2x} \, dx[/tex]
Integrate.
[tex]\frac{-x^3}{3}+x^2\\(\frac{-2^3}{3}+2^2)-[\frac{-0^3}{3}+0^2]\\-\frac{8}{3} +4-0\\-\frac{8}{3}+\frac{12}{3} =4/3[/tex]
Using Desmos I have Graphs of both of the equations you have provided. The problem asks us to find the shaded region between those curves/equations.
Proof Check your interval of x.
