Select the correct answer in each of the following

A, A and A

Step-by-step explanation:

Given

y = ax² + bx + c ( a ≠ 0 )

• If a > 0 then vertex is minimum

• If a < 0 then vertex is maximum

The graph here is a maximum, thus a < 0 → A

The value of c is the y- intercept of the graph ( when x = 0 )

Since the y- intercept is below the x- axis then c < 0 → A

The solutions to the equation are where the graph crosses the x- axis ( y = 0 )

Since the graph crosses the x- axis to the left of the y- axis, then

both solutions are negative → A

because they could drop even lower..

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
