Answer:
A
Step-by-step explanation:
You're looking for x-intercepts
From the graph you know that the x-intercepts are as follows:
x = -4, x = -2, x = 4
And this is when y or f(x) = 0
so you can rewrite each x-intercept as an equation
0 = x + 4
0 = x + 2
0 = x - 4
Now you know each of the terms
f(x) = (x-4)(x+2)(x+4)
Answer:
Olga's mistake was in Step 3 because she divided the entire equation by 3 instead of dividing it by 1/3.
Answer:
11x+16y = 13
16y = -11x+13
y = -11/16x+13/16
