Which ordered pair in the form (a, b) is a solution of this equation?
3a – 4b = 21
a.
(–3, –2)
b.
(0, 7)
c.
(–2, –3)
d.
(7, 0)

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
