Answer:
B
Step-by-step explanation:
Given
f(x) = 3(x + 1)(x - 7) ← expand the factors using FOIL
= 3(x² - 6x - 7) ← distribute the parenthesis
= 3x² - 18x - 21 → B
Answer:
$212.24
Step-by-step explanation:
Start: $200
After 1 year: $200 * 1.02 = $204
After 2 years: $204 * 1.02 = 208.08
After 3 years: $208.08 * 1.02 = $212.24
Answer: $212.24
Answer:
The zeros are
Larger
Smaller 
2)The vertex is (-12.5,-2.25)
Step-by-step explanation:
The given function is:

This function is already in the factored form therefore it is easy to find the zeros,

Either
or 
The zeros are
or 
b) The expanded form of the given function is:

We obtain the vertex form by completing the square:

The vertex form is:

Therefore the vertex is (-12.5,-2.25)
