I know that the thing is safe, but I can't download and see. I don't know why.
Vertex is at (-3,-1) so expressing the quadratic function in vertex form:
f(x) = a(x -(-3))^2 + (-1)
= a(x+3)^2 -1
also note when x=0, f(0)=8
8 = a(3)^2 -1 = 9a-1
so a=1
f(x) = (x+3)^2 - 1
= x^2 + 6x + 9 -1
= x^2 +6x + 8
I would say all of them can be model as functions.
<span>model number:
This would be a onto function, meaning that the outputs are not unique.
f(model_1) = f(model_2) = computer_type.
</span><span>part number:
</span>This would mean the function takes in multiple parameters.
f(part_1, part_2, part_3, ...) = computer
<span>serial number:
This is the most obvious one; an one-to-one function:
f(s_num_1) = computer_1;
f(s_num_2) = computer_2;</span>
Hey there!
10(a - 2.5 + 0.56b)
= 10(a) + 10(-2.5) + 10(0.56b)
= 10a - 25 + 5.6b
= 10a + 5.6b - 25
Therefore, your answer is: 10a + 5.6b - 25
Good luck on your assignment and enjoy your day!

Answer:
No.
Step-by-step explanation:
It's not reasonable because 0.42 in decimals makes it smaller because of more digits.
