Question

Select the correct answer in each of the following

Answer 1

Number 1 is B , number 2 is A n number 3 is A

Answer 2

A, A and A

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
