it's third option the one who says 10 units up
Step-by-step explanation:
h and p are the number of history and psych textbooks, respectively.
store sold a total of 411 textbooks in a week.
h + p = 411
The number of history textbooks sold was 69 less than the number of psychology textbooks sold.
h = p - 69
Substitution
(p-69) + p = 411
2p = 411+69
p = 240
h = p-69 = 171
171 history books and 250 psych books
{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).Answer:
Step-by-step explanation:Answer:
The correct option is 2.
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.
