Pls help lol in the xy-plane, the graph of the function f(x) has zeros -5, -2, and 2

which of the following could define f(x) ?

1. f(x)=(x-5)(x-2)(x+2)
2. f(x)=(x-5)(x-2)^2
3. f(x)=(x-2)(x+2)(x+5)
4. f(x)=(x-2)^2(x+5)

Which sum or difference identity would you use to verify that cos (180° - ∅) = -cos ∅? a. sin (α -β) = sin α cos β – cos α sin β b. cos (α -β) = cos α cos β – sin α sin β c. cos (α -β) = cos α cos β + sin α sin β d. sin (α + β) = sin α cos β + cos α sin β
