Moriah, this function is C)neither. in determining whether a function is odd or even: if f(-x)=f(x) then the function is even (example y=2x2, plug in 2 and -2 and the answer is the same y=8) if f(-x)=-f(x) then the function is odd (example y=5x3, plug in 2 and -2 and the answer...
Brenda, if I am reading this correctly, your equation looks as such -1≤X<8 If that's the case, you would draw a solid, vertical line intersecting the x-axis at x=-1 and another dashed vertical line intersecting the x-axis at x=8. Then, shade the area to the right of the solid line and...
