Answer:
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
substitute in the formula above
21 = 4.8
8 x 2.1 = 16.8 - 12 = 4.8
graph A
no x-intercept
no y-intercept
H.A is y = 5
V. A. is x = 0

Answer: 
<u>Step by step explanation:</u>
log₆(5x + 6) - log₆(x - 4) = 2
log₆
= 2
= 6²
= 36
5x + 6 = 36(x - 4)
5x + 6 = 36x - 144
6 = 31x - 144
150 = 31x
= x

Answers:
- a. (-1, -5)
- b. up
- c. x = -1
- d.

- e. -2
- f. see attachment
- g. domain (-∞, ∞) range [-5, ∞)
<u>Explanation:</u>
f(x) = 3x² + 6x - 2
a=3 b=6 c=-2
x = 
Axis Of Symmetry: x = -1
f(-1) = 3(-1)² + 6(-1) - 2
= 3 - 6 - 2
= -5
Vertex: (-1, -5)
