F(x) = _____

1 answer:

4 0

The answer is choice A.

The vertex of the parent function has been shifted 3 units to the left and 4 units up. This is represented by the function f(x) = (x-3)^2 + 4

Note how y = 1(x-3)^2 + 4 is in the form y = a(x-h)^2 + k
(h,k) = (3,4) is the vertex

Carly wants to add texting to her cell phone plan. She has two choices in texting packages. The TURKEY plan charges $.15 per tex

Usimov [2.4K]

Let x be the number of texts (amount of texts) Carly does in a month.

Let y be the "total" amount Carly will have to pay in a month.

Then, as per the TURKEY plan, Carly's monthly total cost will be represented by the equation as shown: $y=0.15x+20$

As we can clearly see in the above equation even if Carly does not text a single message (when x=0), even then they will have to pay $20 for that month.

For the GOBBLE plan, the equation will be: $y=0.2x$ .
