Y = 2x^2 + 4 written in function notation is f(x) = 2x^2 + 4
Answer:
y=6 is the correct answer
460= 40+ 12x
X equal the cost per month, which is what we're looking for.
460=40 +12x
-40 -40
420=12x
420/12= 35
So they would pay $35 per month with the $40 fee, as seen in the $460 fee.

The last statement "Graph B is a valid density curve because the curve is above the horizontal axis, and the area under the curve is 1." is the correct statement.
A few fundamental principles apply to density curves:
- A density curve's area beneath it represents probability.
- A density curve's area under it equals one.
- Base x height in a uniform density curve equals one.
- The likelihood that x = a will never occur.
- The likelihood that x < a is the same as that of x ≤ a.
Following the rules above, we can see from graph B that the curve is above the horizontal axis. That shows that the probabilities are positive which is a necessity. Moreover, the area under the curve must also be 1. That is also satisfied.
Hence, the last statement "Graph B is a valid density curve because the curve is above the horizontal axis, and the area under the curve is 1." is the correct statement.
