Answer:
-3/4
Step-by-step explanation:
I hope this helps.
The function
is a quadratic function due to the highest exponent being 2.
Given functions are:




<h3>What is a quadratic function?</h3>
A function of the form
with
is called a quadratic function means the highest exponent of polynomial should be 2.
Let us check one by one.

Highest exponent =2
The function is also of form
so u(x) is a quadratic function.
The functions v(x), y(x), and z(x) are having highest exponents as 3,5, and 3 respectively so they are not quadratic functions.
Hence, the function
is a quadratic function due to the highest exponent being 2.

Answer:
It's A, c =2.5d
Step-by-step explanation:
When it comes to problems like this, I usually look through the answers and try to plug in the numbers until I get the right equation that fits with the graph.
2.5(5) = 12.5
2.5(10)= 25
2.5(15)= 37.5
2.5(20) = 50
2.5(25) = 62.5
If you compare this to the graph, you'll notice the solutions are the same as the Total Cost (c). That's because c= 2.5d is the right equation for this graph. (Sorry if my explanation is confusing)
