4) DJ determines the zeros of the function f(x) to be -6 and 5. What could be DJ's function? 1. f(x) = (x+5)(x+6)
2. S(x) = (x+5)(x-6)
3. f(x) = (x - 5)(x+6)
4. f(x) = (x - 5)(x-6)

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
