If x-1 is a factor of P(x) = x - 7x²+15x –9, which of the following represents the complete factorization for P(x)?
A. (1-3)(x - 3)(x-1)
B. (x-3)(+4)(+1)
C. (x − 3)(x+3)(x-1)
D. (1-3)(x+3)(x+1)

A. we need the of a software in order for us to graph this function. i used ms excel as shown in the attached picture. just substitute values of t to determine the corresponding b values. then, plot b against t.b. the graph shows an exponential growth. you'll know this by looking at the trend. at t=0, there are 50 bacteria. as time goes on, it increases exponentially. thus, it is called an exponential growth.c. substitute t=5 to the equation: b = 50(1.4⁵) = 268.912there are around 269 bacteria.
