2. Which sequence could be generated by an exponential function? a) 4,7,12,19,... b) 5,9,13, 17,... c) 7, 14, 28,56,... d) 36, 24,4, -24, ...​

C

Step-by-step explanation:

It doubles after every number in the sequence

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

the two may have that, even a breakdown is probably offered
