Answer:
The intercepts of the third degree polynomial corresponds to the zeros of the equation
y = d*(x-a)*(x-b)(x-c)
Where a, b and c are the roots of the polynomial and d an adjustment coefficient.
y = d*(x+2)*(x)*(x-3)
Lets assume d = 1, and we get
y = (x+2)*(x)*(x-3) = x^3 - x^2 - 6x
We graph the equation in the attached file.
We are given parent function:
We need to explain which graph would represent f(x) +1. function.
Please note: 1 is added to parent function f(x).
According to rule of transformations y= f(x)+K shifts K units up of parent function f(x).
For parent function f(x) =2^x, y-intercept is 1.
So, for f(x)+1 function y-intercept would be 2 because y-intercept 1 is being shifted 1 unit up, that is 2.
So, the shown graph would be correct graph for f(x)+1.
