Which of the following sets represents the domain of the function shown? (5 points) {(2, 7}, (15, 13), (21, –4), (24, 18)}

a
{–4, 2, 7, 13, 15, 18, 21, 24}

b
{(7, 2), (13, 15), (–4, 21), (18, 24)}

c
{2, 15, 21, 24}

d
{–4, 7, 13, 18}

c {2, 15, 21, 24}

Step-by-step explanation:

The domain is the input values

Domain {2,15,21,24}

55? i think maybe

step-by-step explanation:

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
