Answer:

Domain = all real numbers

Range = y ≥ -4

Step-by-step explanation:

Domain is the x-values, and for parabolas it is almost always all real numbers.

Range is the y-values, and the lowest it gets is -4.

2[7+2(6.8-4)] whatbis the answer
vagabundo [1.1K]

Answer:

25.2

Step-by-step explanation:

A calculator will evaluate this for you. If you don't have one, you can use a Google search box.

The Order of Operations tells you to start evaluation with the inner parentheses. Multiplication is performed before addition.

2(7 +2(2.8))

= 2(7 +5.6)

= 2(12.6)

= 25.2

Which function is graphed?
Alexandra [31]

Hey there! :)

Answer:

C. {x² + 4, x < 2

    {-x + 4   x ≥ 2

Step-by-step explanation:

This is a piecewise function, where the two equations are different. They are:

y = x²+ 4

y = -x + 4

The function x² + 4 is graphed where x < 2. (< is used because the circle is open)

The function -x + 4 is graphed where x ≥ 2. (≥ is used since the endpoint is closed)

Therefore, the correct answer is:

C. x² + 4, x < 2

   -x + 4   x ≥ 2

Answer:

4(a). C= 3 + 1.5x

b. 'x' stands for the number of times the cup is refilled.

c. 3 + 1.5 (5)= $10.50

d. My answer to part (c) makes sense because the price of the cup is $3, and I have to pay $1.50 for each additional refill, in accordance to the formula I wrote.

Step-by-step explanation:

The original price of the cup is 3 dollars, but with each refill you get, you have to pay $1.50.
