The function and its inverse are exactly the same. You find the inverse of a function by switching the x and the y and then solving for the new y. If your function is y = -x + 5 and you switch the x and the y, you get x = -y +5. Now solve for the new y to get y = -x + 5. The domain and range for those is all real numbers.

Answer:
The cup can hold 235.5 cubic cm of popcorn.
Step-by-step explanation:
A cone shaped popcorn cup has a radius of 5 cm and a height of 9 cm.
Use 3.14 as an approximation for pi.
Now, to find cubic cm of popcorn the cup can hold.
Radius (r)= 5 cm
Height (h)= 9 cm
= 3.14 (as per question).
So, to get the cubic cm of popcorn the cup can hold we put formula of volume:
Volume=
r
h
3
Volume= 3.14 x 5
× 9
3
Volume= 3x14 x 25 x 3
Volume= 235.5 cubic cm.

I THINK MAYBE C hope this helps
Step-by-step explanation:

Taking 4 out from first two terms, we will get

Now we divide the coefficient of x by 2 and add and subtract the square of the result, we will get

Distributing 4

Cancelling 9

And that's the required standard form.
