Answer: It is B
Step-by-step explanation:
Just took the test
F(x) = 3x² + 6x - 1
The graph is a parabola open upward (a= 3>0) with a minimum.
Calculate the vertex:
x = -b/2a → x = -6/(2.3) = -1. Then the axis of symmetry is x = - 1
Now to calculate the minimum, plugin the value of x:
y = 3x² + 6x - 1
y = 3(-1)² + 6(-1) -1
y= 3 - 6 -1 and y = - 4,
Ten the vertex (minimum) is at (-1,- 4)

Answer:
$30
Step-by-step explanation:
If the CD paid back 3% interest of the money you put in, all you have to find is what 3% of $1000 is.
3% = 0.03.
0.03 x 1000 is $30.
You earned $30 in interest.
Answer:
This needs more information for it to be solved.
Step-by-step explanation:
Are there answer choices?
or a chart with specific information of the appropriate measurements that can be put into the equation to solve it?
I wish i could give you a proper answer, but without the numbers I can't answer this for you. I'm sorry.
