Answer:
I think its 8 but I'm not positive sorry if I'm wrong!
Step-by-step explanation:
The Y-intercept is when the line of the graph crosses through the y intercept
You're correct, the answer is C.
Given any function of the form

, then the derivative of y with respect to x (

) is written as:

In which

is any constant, this is called the power rule for differentiation.
For this example we have

, first lets get rid of the quotient and write the expression in the form

:

Now we can directly apply the rule stated at the beginning (in which

):

Note that whenever we differentiate a function, we simply "ignore" the constants (we take them out of the derivative).
