Answer:
it is 7
Step-by-step explanation:
The answer to this question is 6 1/4. This is because the vertex of this function has a y-coordinate of 6.25, which is 6 1/4 in mixed fraction form.
Answer:
20 orders: 1/2 The cupcakes would be: 1/5 and songs would be: 1/4
Step-by-step explanation:
I'm so sorry if I get this wrong! I'm pretty sure im correct but not positive
Answer: 3/10
Step-by-step explanation:
Take the derivative of
to get
. Set that equal to 0 to find the critical points of the function. The critical points is when the slope is either 0 or undefined.
Now do:

There are quite a few more steps to actually find the minimum, but for this example you can automatically assume its a minimum because it is the only critical point of the function. Ill show you these extra steps tho.
Plug in two numbers into the derivative. One that is less than 3/10 and one that is greater than 3/10. The numbers 0 and 1 are fine. When x = 0, the function is -6. When x = 1, the function is +14. A switch from negative to positive indicates a minimum value
