What function has a range of y<5

{y|y ≤ 5}. It means the maximum value of the function is 5. It is possible if the vertex of a downward parabola is in the form of (h,5).

Step-by-step explanation:

The correct option is 2.

Step-by-step explanation:

The range of a parabola is {y|y ≤ 5}.

It means the maximum value of the function is 5. It is possible if the vertex of a downward parabola is in the form of (h,5).

The vertex form of a parabola is

Where, (h,k) is vertex and a is a constant.

If a<0, then f(x) is a down ward parabola and if a>0, then f(x) is an upward parabola.

In option 1,

It is an upward parabola with vertex (4,5), therefore the range of the function is {y|y ≥ 5}. Option 1 is incorrect.

In option 2,

It is a downward parabola with vertex (4,5), therefore the range of the function is {y|y ≤ 5}. Option 2 is correct.

In option 3,

It is an upward parabola with vertex (5,4), therefore the range of the function is {y|y ≥ 4}. Option 3 is incorrect.

In option 4,

It is a downward parabola with vertex (5,4), therefore the range of the function is {y|y ≤ 4}. Option 4 is incorrect.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
